ChipScope Pro实例教程宋存杰1. ChipScope Pro简介ChipScope Pro的主要功能是通过JTAG口、在线实时地读出FPGA的内部信号。

基本原理是利用FPGA中未使用的BlockRAM，根据用户设定的触发条件将信号实时地保存到这些BlockRAM中，然后通过JTAG口传送到PC机，显示出时序波形。

一般来说，ChipScope Pro在工作时需要在用户设计中实例化两种核：一是集成逻辑分析仪核（ILA core，Integrated Logic Analyzer core），提供触发和跟踪捕获的功能；二是集成控制器核（ICON core，Integrated Controller core），负责ILA核和边界扫描端口的通信，一个ICON核可以连接1~15个ILA核。

ChipScope Pro工具箱包含3个工具：ChipScope Pro Core Generator（核生成器）、ChipScope Pro Core Inserter（核插入器）和ChipScope Pro Analyzer（分析器）。

ChipScope Pro Core Generator的作用是根据设定条件生成在线逻辑分析仪的IP核，包括ICON核、ILA核、ILA/ATC2核和IBA/OPB核等，设计人员在原HDL代码中实例化这些核，然后进行布局布线、下载配置文件，就可以利用ChipScope Pro Analyzer设定触发条件、观察信号波形。

ChipScope Pro Core Inserter除了不能生成IBA/OPB核和ILA/ATC2核以外，功能与ChipScope Pro Core Generator类似，可以生成ICON核和ILA核，但是它能自动完成在设计网表中插入这些核的工作，不用手工在HDL代码中实例化，在实际工作中用得最多。

下图为ChipScope的两种使用流程图，左侧为使用ChipScope Pro Core Generator流程。

第11章片内逻辑分析仪工具——ChipScope Pro11.1 ChipScope Pro工具介绍在FPGA调试阶段，传统的信号分析手段要求在设计时保留一定数量的FPGA管脚作为测试管脚，这种方法灵活性差，对PCB布线也有一定的影响。

当今先进的FPGA器件所具有的规模、速度和板级要求使得利用传统逻辑分析方法来调试采用FPGA器件进行的设计几乎是不可能的。

Xilinx公司推出的片内逻辑分析仪ChipScope Pro能够通过JTAG口，实时地读出FPGA的所有内部信号，而只需要片内的少量BlockRAM和逻辑资源，使得逻辑分析灵活方便。

ChipScope Pro是与ISE配套使用的，其版本经过了ChipScope 4.1i，ChipScope 4.2i，ChipScope Pro 5.1i，ChipScope Pro 5.2i和ChipScope Pro 6.1i的升级过程，ChipScope Pro 6.1i是与ISE 6.1配套使用的最新版本。

ChipScope Pro软件由3个工具组成：(1) ChipScope Pro内核生成器：为综合控制器（ICON）内核、CoreConnect™ OPB的总线分析内核（IBA/OPB）、逻辑分析（ILA）内核及安捷伦跟踪内核（ILA/ATC）提供网表和实例化的模板；(2) ChipScope Pro内核插入器：自动地为用户已经综合完的设计中插入ICON、ILA和ILA/ATC的内核；(3) ChipScope Pro分析仪：提供器件的配置、触发的设定和ILA、IBA/OPB及ILA/ATC核的踪迹显示功能。

各种内核实现了信号的触发和捕获，而ICON内核专门用于与边界扫描（Boundary Scan）管脚的通信。

使用ChipScope Pro工具的设计可以容易地同任何标准的FPGA设计流程结合起来，其中要用到标准的HDL综合工具和Xilinx ISE的实现工具，设计流程如图11.1所示。

ChipScope使用方法说明拟制李雷鸣日期2005-6-41 ChipScope简介ChipScope的主要功能是能通过JTAG口，在线、实时地读出FPGA内部逻辑的任何信号。

其基本原理是利用FPGA中未使用的Block Ram，将想要观察的信号（寄存器，网线）实时地存到这些BlockRam中，然后根据用户设定的触发条件生成特定的地址译码选择数据读出，送到JTAG口，然后在计算机中根据这些数据动态地画出时序波形来。

使用ChipScope分析FPGA内部信号的优点如下：1. 成本低廉，只要有这套软件加上一根JTAG电缆就可完成信号的分析。

2. 灵活性大，可观测信号的数量和存储深度仅由器件剩余的Block Ram数量决定。

剩余Block Ram越多，可分析的信号的数量和存储深度就越大。

3. 使用方便，该软件可以自动读取原设计生成的网表（*.ngc,*.edf,*.edn）区分时钟信号和普通信号，待观测信号的设定也十分方便，存储深度可变。

可以设计多种触发条件的组合。

然后软件自动将其IP核的网表插入到原设计的网表中。

其IP核只使用少量的查找表资源和寄存器资源，对原设计的影响很小。

4. 使FPGA不再是“黑箱”。

Chip Scope 可以十分方便的观测FPGA内部的所有信号，包括寄存器，网线型，甚至可以观测综合器产生的重命名的连接信号，使FPGA不再是“黑箱”，对FPGA内部逻辑调试非常方便。

2 ChipScope组成ChipScope工具箱包含三个工具：ChipScope Core Generator, ChipScope Core Inserter,和ChipScope Analyzer。

ChipScope Core Generator的作用是根据设定条件生成在线逻辑分析仪的IP核。

使用方法和Xilinx的Core Generator相似。

ChipScope Core Inserter完成读取并分析原设计的网表，设置待分析信号，设定触发条件，和自动生成的该在线逻辑分析仪lP核的网表，并将网表插入到原设计的网表中去。

Click Next and then click New ILA Unit. Notice in the left hand window how an instance of the ILA core, U0:ILA, is added to the system.Genesys 6-4 /universityFigure 4. Insert a new integrated logic analyzer (ILA) Unit2-1-3. Click Next to setup the trigger parameters.Each ILA or ILA/ATC core can have up to 16 separate trigger ports that can be setup independently. The individual trigger ports are buses that are made up of individual signals or bits that can range from 1 to 256 bits. Each trigger port can be connected to 1 to 16 match units. A match unit is a comparator that is connected to a trigger port and is used to detect events on that trigger port. The results of one or more match units are combined together to form the overall trigger condition event that is used to control the capturing of data. The different comparisons or match functions that can be performed by the trigger port match units depend on the type of match unit. The ILA and ILA/ITC cores support six types of match units. In this lab, you will setup the ILA core to trigger via some UART control signals.2-1-4. Set the following ILA trigger parameters as follows and then click Next.Trigger Input and Match Unit Settings.• Number of input trigger ports: 3Trigger Port Trigger Width # Match Units Counter WidthMatch Type TRIG0 1 1 Disabled Basic TRIG1 1 1 Disabled Basic TRIG211DisabledBasicTrigger Condition Settings• Enable Trigger Sequencer: Checked (This allows you to specify a sequence of events to enable triggering)•Max Number of Sequencer Levels: 2Storage Qualification Condition Settings• Enable Storage Qualification: Checked (This allows you to specify which data will be stored in the internal buffer)Figure 5. Specify the Trigger ParametersThe maximum number of data sample words that the ILA core can store in the sample buffer is called the data depth. The data depth determines the number of data width bits contributed by each block RAM unit used by the ILA unit. The maximum number of data sample words that can be captured depends on the number and size of block RAM, which varies according to device family and density.2-1-5. Set the following capture parameters and click Next.• Data Depth: 1024• Sample On: Rising clock edge• Data Same as Trigger Port: unchecked• Data Width: 8Figure 6.

ChipScope Analyzer WindowEach ChipScope Pro ILA, ILA/ATC, and IBA core has its own Trigger setup window, which provides a graphical interface for the user to setup triggers. The trigger mechanism inside each ChipScope Pro core can be modified at run-time without having to recompile the design. There are three components to the trigger mechanism:• Match Functions: Defines the match or comparison value of each match unit• Trigger Conditions: Defines the overall trigger condition based on a binary equation or sequence of one or more match functions• Capture Settings: Defines how many samples to capture, how many capture windows, and the position of the trigger in those windowsIn this design, you will setup the triggers to capture text at the PicoBlaze output port, after being entered via Hyper Terminal.3-1-7. Specify the Match Units as follows:• M0:TriggerPort0 (data_present): Value 1• M1:TriggerPort1(read_from_uart): Value 1• M2:TriggerPort1(write_to_uart): Value 1Figure 15. Setup the Match Units3-1-8.

These guidelines are based on Micron recommendations and board level simulation.•Dedicated bus with matched trace lengths (+/- 100 mils)•Memory clocks routed differentially•50 ohm* controlled trace impedance•Series termination on bidirectional signals at the memory device•Parallel termination following the memory device connection on all signals•100 ohm* pull-up resistor to the termination supply on each branch of shared signals (control, address)•Termination supply that can source both termination and reference voltages.* Ideal impedance values. Actual may vary.Some of the design considerations were specific to the Virtex-5 architecture. For example, the data strobe signals (DQS) were placed on Clock Capable I/O pins in order to support data capture techniques utilizing the SERDES function of the Virtex-5 I/O blocks. The appropriate DDR2 memory signals were placed in the clock regions that correspond to these particular Clock Capable I/O pins.The DDR2 signals are connected to I/O Banks 11 and 13 of the Virtex-5 FX30T FPGA. The output supply pins (VCCO) for Banks 11 and 13 are connected to 1.8 Volts. This supply rail can be measured at test point TP5, which can be found in the area around the power modules. The reference voltage pins (VREF) for Banks 11 and 13 are connected to the reference output of the Texas Instruments TPS51116 DDR2 Power Solution Regulator. This rail provides the voltage reference necessary for the SSTL_2 I/O standard as well as the termination supply rail. The termination voltage is 0.9 Volts and can be measured at test point TP6.The following table contains the FPGA pin numbers for the DDR2 SDRAM interface.Signal Name Virtex-5 pin Signal Name Virtex-5 pinDDR_A0 U25 DDR_D0 R22DDR_A1 T25 DDR_D1 R23DDR_A2 T24 DDR_D2 P23DDR_A3 T23 DDR_D3 P24DDR_A4 U24 DDR_D4 R25DDR_A5 V24 DDR_D5 P25DDR_A6 Y23 DDR_D6 R26DDR_A7 W23 DDR_D7 P26DDR_A8 AA25 DDR_D8 M26DDR_A9 AB26 DDR_D9 N26DDR_A10 AB25 DDR_D10 K25DDR_A11 AB24 DDR_D11 L24DDR_A12 AA23 DDR_D12 K26DDR_D13J26J25 DDR_D14DDR_BA0 U21 DDR_D15 N21DDR_BA1 V22M21 DDR_D16DDR_CS# AD24 DDR_D17 J23ODT AF24 DDR_D18 H23H22 DDR_D19DDR_WE# AA22 DDR_D20 G22DDR_RAS# Y22 DDR_D21 F22DDR_CAS# W24 DDR_D22 F23DDR_CLKEN T22 DDR_D23 E23G24DM0 U26 DDR_D24F24DM1 N24 DDR_D25G25DM2 M24 DDR_D26DM3 M25 DDR_D27H26G26 DDR_D28DQS0 P,N W26, W25 DDR_D29 F25DQS1 P,N L23, L22 DDR_D30 E25DQS2 P,N K22, K23 DDR_D31 E26DDR2_CLK0 P,N V21, W21DDR2_CLK1 P,N N22, M22Table 4 - Virtex-5 FXT DDR2 FPGA PinoutsMemory2.2.2 FlashThe Virtex-5 FXT Evaluation Board has 16 MB of non-volatile flash memory on board. The flash device is made by Intel,part number: PC28F128P30T85. The flash memory interface utilizes a 16-bit data bus and can be accessed directly without any external hardware settings or jumpers.

The clock sources described in this section are used to derive the required clocks for the memory and communications devices, and the general system clocks for the logic design. This section also provides information on how to supply external user clocks to the FPGA via the on-board connectors and oscillator socket.The following figure shows the clock nets connected to the I/O banks containing the global clock input pins on the Virtex-5 FX30T FPGA. Ten out of the twenty global clock inputs of the Virtex-5 FPGA are utilized on the board as clock resources. The other global clock inputs are used for user I/O. It should be noted that single-ended clock inputs must be connected to the P-side of the pin pair because a direct connection to the global clock tree only exists on this pin. The I/O voltage (VCCO) for Bank 3 is set at 3.3V. Bank 4 is jumper selectable via JP2 to either 2.5V or 3.3V. In order to use the differential clock inputs as LVDS inputs, the VCCO voltage for the corresponding bank must be set for 2.5V since the Virtex-5 FPGA does not support 3.3V differential signaling. Single-ended clock inputs do not have this restriction and may be either 2.5V or 3.3V. The interface clocks and other I/O signals coming from 3.3V devices on the board are level-shifted to the appropriate VCCO voltage by CB3T standard logic devices prior to the Virtex-5 input pins.Figure 5 - Clock Nets Connected to Global Clock InputsThe on-board 100MHz oscillator provides the system clock input to the global clock tree. This single-ended, 100 MHz clock can be used in conjunction with the Virtex-5 Digital Clock Managers (DCMs) to generate the various processor clocks and the clocks forwarded to the DDR SDRAM devices. The interface clocks supplied by the communications devices are derived from dedicated crystal oscillators.Reference# Frequency Derived InterfaceClock Derived Frequency Virtex-5 pin#U11 100 MHz CLK_100MHZ 100 MHz E18 U12 (sckt) User defined User Defined User Defined E13 J2, J5User DefinedUser Defined User Defined AB15.

Network access is provided by a 10/100/1000 Mb/s Ethernet PHY, which is connected to the Virtex-5 via a standard GMII interface. The PHY connects to the outside world with a standard RJ45 connector (J1) and is located in the upper right corner of the board.A USB compatible RS232 transceiver is available for use as well. The USB Type B peripheral connector (JR1) is mounted on the top right corner of the board. A second, standard DB9 Serial port (P1) to the embedded processor or FPGA fabric is provided through a dual-channel RS232 transceiver.2.4.1 10/100/1000 Ethernet PHYThe PHY is a National DP83865DVH Gig PHYTER® V. The DP83865 is a low power version of National’s Gig PHYTER V with a 1.8V core voltage and 3.3V I/O voltage. The PHY also supports 2.5V I/O, but the 2.5V option is used on the board. The PHY is connected to a Tyco RJ-45 jack with integrated magnetics (part number: 1-6605833-1). The jack also integrates two LEDs and their corresponding resistors as well as several other passive components. External logic is used to logically OR the three link indicators for 10, 100 and 1000 Mb/s to drive a Link LED on the RJ-45 jack. The external logic is for the default strap options and may not work if the strap options are changed. Four more LEDs are provided on the board for status indication. These LEDs indicate lnk at 10 Mb/s, link at 100 Mb/s, link at 1000 Mb/s and Full Duplex operation. The PHY clock is generated from its own 25 MHz crystal. The following figure shows a high-level block diagram of the interface to the DP83865 Tri-mode Ethernet PHY.Figure 6 - 10/100/1000 Mb/s Ethernet InterfaceThe PHY address is set to 0b00001 by default. PHY address 0b00000 is reserved for a test mode and should not be used. Three-pad resistor jumpers are used to set the strapping options. These jumper pads provide the user with the ability to change the settings by moving the resistors. The strapping options are shown in the following table. The dual-function pins that are used for both a strapping option and to drive an LED, have a set of two jumpers per pin. The dual-function pins are indicated by an asterisk in the table.Function Jumper InstallationResistorMode EnabledJT4: pins 1-2 JT5: pins 1-2 0 ohm 0 ohm Auto-negotiation enabled (default) Auto-Negotiation*JT4: pins 2-3 JT5: pins 2-3 0 ohm 0 ohm Auto-negotiation disabled JT8: pins 1-2 JT9: pins 1-2 0 ohm 0 ohm Full Duplex (default) Full/Half Duplex*JT8: pins 2-3 JT9: pins 2-30 ohm 0 ohm Half DuplexSpeed 1*JT1: pins 1-2 JT2: pins 1-20 ohm 0 ohmSpeed 0*JT1: pins 1-2 JT2: pins 1-20 ohm 0 ohm Speed Selection: (Auto-Neg enabled) Speed1 Speed0 Speed Advertised1 1 1000BASE-T, 10BASE-T 1 0 1000BASE-T0 1 1000BASE-T, 100BASE-TX0 0 1000BASE-T, 100BASE-TX, 10BASE-TDefault: 1000BASE-T, 100BASE-TX, 10BASE-T JT9: pins 1-2 JT10: pins 1-2 0 ohm 0 ohm PHY Address 0b00001 (default) PHY address 0*JT9: pins 2-3 JT10: pins 2-3 0 ohm 0 ohm PHY Address 0b00000JT6: pins 1-2 Compliant and Non-comp.

The pin-out for a jumper pad is shown below.The auto-MDIX mode provides automatic swapping of the differential pairs. This allows the PHY to work with either a straight-through cable or crossover cable. Use a CAT-5e or CAT-6 Ethernet cable when operating at 1000 Mb/s (Gigabit Ethernet). The boundary-scan Test Access Port (TAP) controller of the DP83865 must be in reset for normal operation. This active low reset pin of the TAP (TRST) is pulled low through a 1K resistor on the board.

This transceiver operates at 3.3V with an internal charge pump to create the RS232 compatible output levels. This level converter supports two channels. The primary channel is used for transmit and receive data (TXD and RXD). The secondary channel may be connected to the FPGA by installing jumpers on “J3” and “J4” for use as CTS and RTS signals. The RS232 console interface is brought out on the DB9 connector labeled “P1”.Figure 8 - RS232 InterfaceA male-to-female serial cable should be used to plug “P1” into a standard PC serial port (male DB9).

The possible configuration methods include Boundary-scan (JTAG cable), BPI Flash, and the System ACE Module (SAM) header. The Virtex-5 device also supports configuration from BPI Flash. The blue LED labeled “DONE” on the board illuminates to indicate when the FPGA has been successfully configured.JP5 is the mode jumper that is used to tell the FPGA to configure in JTAG mode or Flash BPI mode. In JTAG mode a Xilinx parallel JTAG cable must be used (PC4 or USB). When the jumper is set for BPI mode, the flash must be programmed with a BPI-UP image in order for the FPGA to successfully configure. For configuration from a System ACE Module, the JTAG setting must be used.The Virtex-5 FXT Evaluation Board come pre-programmed with the factory test image in the BPI flash. The table below shows the correct jumper configuration for each configuration mode.ConfigurationModeJP5 PositionJTAG 2-3 System ACE 2-3BPI-UP * 1-2Table 16 - FPGA Configuration Modes*Default assembled state2.7.2 System ACE™ Module ConnectorThe Virtex-5 FXT Evaluation Board provides support for the Avnet System ACE Module (SAM) via the 50-pin connector labeled “JP6” on the board. The SAM can be used to configure the FPGA or to provide bulk Flash to the processor. This interface gives software designers the ability to run real-time operating systems (RTOS) from removable CompactFlash cards. The Avnet System ACE module (DS-KIT-SYSTEMACE) is sold separately.

The JTAG port can also be used as the processor debug port. The FPGA general-purpose I/O pins are used for this interface. The following figure shows the CPU Debug Connector.Figure 11 - CPU Debug Connector2.7.5 CPU Trace PortThe Virtex-5 FXT Evaluation Board provides a CPU Trace header for connection of a trace probe to the integrated PowerPC processor. The FPGA general-purpose I/O pins are used for this interface.The processor uses the trace interface when operating in real-time trace-debug mode. Real-time trace-debug mode supports real-time tracing of the instruction stream executed by the processor. In this mode, debug events are used to cause external trigger events. An external trace tool uses the trigger events to control the collection of trace information. The broadcast of trace information on the trace interface occurs independently of external trigger events (trace information is always supplied by the processor). Real-time trace-debug does not affect processor performance.

如果已有建好的ise工程，可跳过此步骤，打开已有工程即可。

建立工程时注意正确添加.v源文件和.ucf管脚配置文件。

2.插入及配置核这里介绍的是ICON核和ILA核的使用方法。

ILA核提供触发和跟踪功能，根据用户设置的触发条件捕获数据；然后在ICON的控制下，通过边界扫描口将数据上传到PC；最后在Analyzer中显示出信号波形。

2.1运行Ise的Synthesize单击选中sources栏中的顶层源文件，右键点击processs栏中的Synthesize，点击Run，进行代码综合。

Xilinx的Chipscope类似于Altera的Signaltap。

下面记录一下Chipscope的使用方法。

1. 生成Chipscope文件第一步: 打开ISE Design Tools下的CORE Generator工具。

第二步: 在Xilinx CORE Generator的环境中选择菜单File->New Project，在弹出的对话框中选择存放的目录保存即可。

设置如下。

些，呵呵！选完后Apply一下OK关闭。

第五步: 双击IP Catalog窗口的Debug&Verification下的ICON(chipscope Pro –integrated Controller) 。

第六步: 在弹出的窗口中点击Generate就可以了。

第七步: ICON生成完成后，再双击IP Catalog窗口的Debug&Verification下的ILA(Chipscope Pro –Integrate Logic Analyzer)。

第八步: 在ILA的配置可以根据自己的需要来选择，我们这里不强求，我们这里选择一个触发Group，选择数据的采样深度为2048,就是一次采样2048个点，这个深度当然越大越好，但FPGA资源有限啊！设置完后点击Next。

也会用到Chipscope, 这样程序中基本上的信号都能观察了。

设置完后再Generate。

第十步: 这样我们所需的Chipscope文件都已经生成好了，我们可以在eeprom_test 的目录下看到生成的文件，特别要注意下图中我用红色圈出来的文件，如果在其它的工程中我们需要使用Chipscope的话，只要把这四个文件拷过去就好了，不要费老大力气的再重新生成一边。

接下来是Analyzer：点击Open cable按钮建立JTAG连接。

如果开发板和JTAG连接正常的话，Chipscope能找到开发板使用的FPGA芯片。

点击OK把Data Port里的CH0 ~CH７组合成一个组，方法是按Ctrl键，再选择Data port 里的CH0~CH7, 点击右键，选择Move to Bus->New Bus。

Tutorial 11ChipscopePro, ISE 10.1 and Xilinx Simulator on theDigilent Spartan-3E boardIntroductionThis lab will be an introduction on how to use ChipScope for the verification of the designs done on FPGAs. ChipScope Pro 10.1 is the tool provided by Xilinx for this purpose. The board will be a Digilent Spartan-3E starter kit.ObjectiveThe objective is to verify the functioning of a simple counter implementation using ChipScope. The counter implemented here is a 4-bit counter operated at five different frequencies. The aim is not to implement complex digital designs but to show the user a method to integrate ChipScope into an existing design in order to verify its operation in a simple and efficient manner. ChipScope is a virtual logic analyzer.Prerequisites•Basic knowledge about digital design and FPGAs. •Acquaintance with Xilinx ISE 10.1 and Xilinx Simulator tools.•ChipScope is not included in ISE but is a program available through the Xilinx university program.ApplicationThis document is used by students, who are learning FPGA design and verification.Design Overview4-bit counter implemented at five different frequencies using the system clock running at 50 Mhz. The five frequencies are 50Mhz 23,50Mhz 223,50Mhz 224,50Mhz 225,50Mhz 226, (the frequencies are chosen to make the counter action visible through the LEDs, except for the highest frequency which issolely to verify the design in the ISE Simulator).The frequencies are controlled using input signal FREQUENCY connected to three of the available four sliding switches (SW1, SW2 & SW3).The output of the 4-bit counter is connected to four of the available seven LEDs (LD0, LD1, LD2, LD3).An asynchronous reset is also provided to the design which is connected to one of the sliding switches (SW0).Process1. Complete the counter design to implement functionality as explained (provided).2. Verify inputs and outputs with test bench waveform (provided).3. Integrate the ChipScope into the counter design (explained in detail in the Implementationsection).4. Analyze the design using ChipScope (also explained in detailed in the next section). Implementation1.Right click on the top module of the design intended for verification or debugging, and selectnew source. Then select ChipScope Definition and Connection File as shown below.Figure 1: ChipScope Module Selection2.Then give an appropriate name for the file name. Press next and select the hierarchy level atwhich the analysis is intended to be performed and then press next and then do finish.Figure 2: Hierarchy Selection3.The first two steps will cause a new file (with file name as given) to be created in the sourcewindow under the project hierarchy as shown below.Figure 3: ChipScope Module Location4.Double click on this new source file which cause the below window to pop up. Keep the defaultsettings with Use SRLs and Use RPMs as checked.This will enable the tool to use Shift Register LUTs instead of flip flops and multiplexersthereby effectively reducing the size and improving the performance of the core generator.RPMs contain RLOC constraints which define the order and structure of the underlying design primitives. Use of RPMs will enable the tool to use relationally placed macros (like FMAP, HMAP, ROM, RAM, etc) allowing logic blocks to be placed relative to increase speed and use die resources efficiently substituting hard macros with an equivalent that can be simulated directly which again increases the core performance.Figure 4: SRL and RPMs5.Press next and again leave the default conditions i.e., keep the Disable JTAG Clock BUFGInsertion box unchecked.Disabling JTAG clock will cause the implementation tool to route the JTAG clock using normal routing resources instead of global clock routing resources. This might affect the high speed clock signals. So, unless the global resources are very scarce, it should not be disabled. But, disabling might introduce skew.Figure 5: Global Clocks6.Press next and then select the number of trigger ports and their respective widths dependingon the design requirement.Triggers are those signals which initiate or trigger a certain sequence of actions influencing certain signals under consideration.Here, signal FREQUENCY is the only trigger taken into consideration (which is three bits wide) to control the counter output. Therefore, number trigger ports is set to 1 and the width is set to 3.Figure 6: Trigger Options7.Now Match Type should be selected. This defines the type of trigger one wants.For example: Basic mode, triggers depending on the specific value to which trigger is set.Range mode, triggers depending on the range of values in which the trigger is defined.Extended mode triggers depending on one or more occurrences of exact or range of trigger values to which trigger is set. A combinatorial logic (like AND/OR) or conditional logic(IF/THEN) between 2 or more signals can also be implemented into a trigger signal.Since FREQUENCY signal has definite values, Basic mode can be chosen for the Match Type in the present case.Figure 7: Match Type8.Now uncheck or check the Trigger Conditions Settings i.e., Enable Trigger Sequencer andEnable Storage Qualification depending on the design requirements.Enable Trigger Sequencer can be used to enable a 16 level trigger sequencer which aids in configuring a multi level state machine to trigger upon a user defined traversal scheme of match units.Enable Storage Qualification can be used to filter data that is captured based on the user defined conditions that can be combined with trigger events.As the present trigger (FREQUENCY signal) is a simple and straight forward trigger, so both the boxes can be unchecked which saves little amount of logic space on the FPGA as shown below (LUT and FF count).Figure 8: Trigger and Storage Settings9.Press next and depending on the design requirement uncheck or check the Data Same AsTrigger option.If data is not same as trigger then define the Data Width.The Data Depth is defined depending again on the requirements. It is recommended to put maximum limit as it can be adjusted during the analysis phase.Select the Rising or Falling edge of the clock signal depending on whichever edge desired to sample the data.As in the present design, the output data (Q) and trigger (FREQUENCY) are different the Data Same As Trigger icon is unchecked. Since the width of counter is 4-bit, data width is selected as 4. Rising edge is selected for clock edge for sampling data.Figure 9: Data Options10.Press next and then press Modify Connections.Figure 10: Net Connections11.Once Modify Connections is clicked, the below shown window will pop up. Select theappropriate signals from the list of nets and make connections to the respective clock, trigger and data signals.Note: Sometimes certain nets do not show up in the list, which means that duringoptimizations the tool has found that there is more than one net with same logic. As a result it optimizes it to a single net thereby resulting in absence of few wanted nets. This would require more detailed analysis of the design or modification of the same to make the necessary connections for debugging.Once all the connections are made press OK.Then press Return to Project Navigator and Save Project changes.Figure 11: Net Selections12.Now re-implement the design using the Implement Design icon and then do the configurationusing the Configure Target Device icon.Once these steps are done successfully one is ready to analyze the design using the Analyze Design Using ChipScope icon (present along with the implement design and configure design icons in the processes window of the ISE tool). By double clicking this icon the following window will pop up.Figure 12: ChipScope AnalyzerIn the top left hand corner there is an icon which is used to open the JTAG chain, click on this icon and the following window pops up. It shows all the devices it has found in the JTAG chain, press OK.Figure 13: JTAG Chain13.Once the list is accepted by pressing OK the following window shows up. Set the trigger todesign criteria, adjust the data depth to the amount needed and then hit the play button (all of them are marked in red boxes). One can observe all the output signal variations and do the verification as needed.Figure 14: Trigger and data setup14.The data waveform for the sample counter when trigger is set to “000” is as shown below.Note: To observe more changes the sample clock of the ChipScope has been set to the LSB of the 4-bit counter.Figure 15: Waveforms15. Sometimes using the bus plot will be very beneficial to observe certain output signals. This canbe done by selecting all the data ports and tying them into a single bus as shown below.Figure 16: Bus Port Creation16. The bus plot can be viewed by clicking on the bus plot icon as shown below and selecting theappropriate bus signal intended for viewing.Figure 17: Bus Plot17.This is the signal that is directly being tapped from the FPGA on the board unlike the ISESimulator signals which are behavioral simulated (can be observed using the test benchprovided along with the sample project). So one gets to observe how the actual signal isbehaving on the board which is very essential to resolve timing issues in high speed designs. -Merits and Demerits1.The major advantages of ChipScope compared to external logic analyzers are:•Reduces the probe delays in analyzing the signals.•Reduces the circuit performance degradation caused due to probing.•Portable and convenient to analyze circuitry on FPGA.•Cost – logic analyzers can cost over $50,000.2. There are few limitations of ChipScope as compared to external logic analyzers which are:•Availability of resources on the FPGA (which comes into picture for large complex designs).A simple example is the amount of space occupied by the present counter design with andwithout ChipScope logic integrated respectively is:Figure 18: Device Utilization with ChipScopeFigure 19: Device Utilization without ChipScope•Sampling rate cannot be faster than the design clock frequency (making glitch detection not possible).ExerciseTry to develop a sine wave generator using LUT, CORDIC or any other technique and verify the same using ChipScope Pro tool.Hint: Using bus plot as shown below:-Author BioName: Vallabh Srikanth DevarapalliGraduate student at UNM in ECE department.E-mail: vsdevara@.Updated By:Brian ZufeltUndergraduate student at UNM in ECE department.。

Chipscope的使用本来论文都差不多了，但是老师说缺少实验数据，没有办法，自己再加班加点补吧。

好在自己恰好有ChipScope的盘，于是赶快安装上，临阵磨枪，突击看了一晚上，有了一点点概念，这次记一下，下次就不用绞尽脑汁了。

还要感谢King帮忙查找资料。

逻辑分析仪的产生有两种方法：Core Generator（核产生器）和Core Inserter（核插入器），第一种方法产生内核，将这些内核例化后添加到原设计文件，最后综合，实现，下载。

第二种方法不需要修改原文件，它是将生成的内核添加到综合后的网表文件中，所以我们采用第二种方方法。

Core Inserter 的流程为：1）的RTL 综合成Netlist；2）调用Core Inserter 插入逻辑分析仪；3）布置和布局；4）产生bit 文件下载验证。

1. 首先用ISE对所设计的文件进行综合，然后再添加新建文件，选择ChipScope Definition 文件，选择完毕之后，添加到ISE工程。

2.对core Inserter进行配置，选择器件族，其它的默认即可，接下来是选择数据位宽，捕捉对比，进行信号连线等配置，可以根据自己的情况详细设置。

需要注意的是综合的设置需要保存Keep Hierarchy，防止优化过度。

3.按照以前运行ISE的步骤即可，知道最后下载到FPGA开发板，在ISE的最后会有ChipS cope Pro Analyze，然后点击，就运行逻辑分析仪。

然后点击JTAG连接方式，我的是用U SB的，然后选择[Device] configure 进行器件配置。

在window菜单下面可以选择触发设置窗口等选项，然后运行就可以观察你想要的波形了。

搭建Xilinx开发环境（3）…… 使用ChipScope进行调试Xilinx的ChipScope工具就相当于Altera的SignalTap II，能够捕捉FPGA内部的信号，方便了调试过程。

XILINX Ipcore 之RAM用法指南一RAM分类XILINX的RAM可分为三种，分别是：单口RAM，简化双口RAM和真双口RAM。

如下图所示：图.1 单口RAM图.2 简化双口RAM A口写入数据，B口读数据图.3 真双口RAM A,B任意一个口都可以读写数据，可从A写入，B读数据二选择数据位宽和深度Block RAM的数据位宽为1-1152bit，深度取决于所选择FPGA器件中block的数量。

超出地址范围之外的写操作，写进去的数据不会与存储器件中的数据冲突。

读超出地址范围之外数据将会返回无效数据。

注意，当对超出范围的地址进行操作的时候，不能置位set或reset 信号，因为这仍然会读出无效数据。

三操作模式每个端口的操作模式决定了此端口的读和写之间关系。

端口A和B可以独立配置为以下三种模式中任一模式：写优先模式，读优先模式，不改变模式。

这些模式详解见下面。

当A和B端口地址有冲突时，操作模式就会影响A和B口之间关系。

1．写优先模式(write first mode)：在写优先模式中，输入数据被自动写入存储器件中，并且出现在数据输出端口。

时序见下图。

这种传输模式增强了在同一端口写操作时使用数据输出总线的灵活性。

图.4 写优先操作模式2．读优先模式(read first mode)：在读优先模式中，预先存储在写地址中的数据会被输出，而输入数据被存入存储器件中。

这种模式见下图。

图.5 读优先模式3．不改变模式：在不改变模式中，输出锁存在写操作时候保持不变，见下图。

在同一端口的写操作不会对数据输出端口产生影响，输出仍然是以前的读数据。

图.6 不改变模式四数据位宽比例Block RAM产生器支持端口A和B的位宽不同。

即DINA,DINB,DOUA,DOUTB位宽可以互不相同。

支持1:32到32:1之间的比例，端口A的宽度最大可达端口B的32倍，反之亦然。

例如一个A口位宽32bit深度2048的真双口RAM，如果B端口宽度为8bit深度为8192。

chipscope的学习与使用(1) chipscope有三个主要的功能：1、ChipScope Core Inserter配置ICON核配置ILA核触发参数、捕获参数、网线连接2、ChipScope Pro Analyzer初始化边界扫描链，选择芯片型号配置芯片(JTAG CLOCK)设置触发条件观察信号波形3、ChipScope Pro Generator生成ICON核生成ILA核通过功能1生成了一个CDC文件，在这个CDC文件中需要配置一下触发参数的个数、深度以及连接。

最后工程需要重新run一下。

功能1通过后，可以双击Analyze Design Using ChipScope来启动分析仪，通过分析仪可以查看CDC 文件中配置的连线的波形。

功能3是一个集成功能，它把功能1和功能2集成为一个功能。

功能3需要打开ChipScope Pro Generator软件，在这个软件中新建一个工程，配置芯片型号以及合适的语言(Verilog HDL)，配置ICON核和ILA核。

之后在工程中加入这两个文件：xxx_icon.xco和xxx_ila.xco文件在工程.v文件中加入ICON核和ILA核的调用，这时不需要把cdc文件，而且CDC文件需要从工程中移除。

下面是一个小的例子(调用ICON核和ILA核)：wire [w_icon-1 : 0] con;wire [w_trig-1 : 0] p_data;xxx_icon u_icon(.CONTROL0(con));xxx_ila u_ila(.CLK(clk),.CONTROL(con),.TRIG0(p_data));最后再打开分析仪就可以来查看波形了，如果需要有时候可以再次加载CDC 文件。

以下是具体的操作说明：ChipScope Pro Generator打开方式：(见图《软件打开》)开始->程序->Xilinx ISE Suite 12.4->ISE Design Tools->CORE Generator打开这个软件后，新建一个工程。
