BitRunner V2 Quick-Start GuideThe Carbide 3D BitRunner V2 automates your router’s on/off functionality in Carbide Motion. No more reaching into the work envelope with a moving end mill. Now you can power down your router with the touch of a button—allowing you to perform tool changes quickly and safely. Use the BitRunner V2 in conjunction with the BitSetter and BitZero to automate your cutting process even more.BitRunner V2 comes in deluxe and standard versions. While both versions have the same functionality, the deluxe version comes with an EMI filter not included in the standard.Shapeoko Pro, Shapeoko 4, and Shapeoko 3 models that shipped with the Z-Plus as standard equipment are ready for BitRunner V2 right out of the box. Users with Shapeoko 3 models with Carbide Motion boards 2.3 and earlier (machines purchased before Black Friday 2019) will need to have pu rchased a new “Carbide Motion PCB –with Enclosure” at checkout. See Install a New Carbide Motion Board (v2.3 or earlier).We’re here to help! If you encounter any issues while setting up or using your BitRunner V2, please contact the Carbide 3D support team at: *********************.Important Software InformationYou must run Carbide Motion 4 or later with the BitRunner V2. Download the most recent version of Carbide Motion from: /carbidemotion/download/.Do Not Connect to Ethernet-Enabled DevicesWhile an Ethernet cable is used to connect the control pendant to the BitRunner V2, the BitRunner V2 is NOT an Ethernet device.Setting Up the BitRunner V21.1 Review BitRunner V2 Kit ContentsFigure 1Item Description Qty NoteA BitRunner V2 (Deluxe or Standard) 1 BitRunner V2 enclosure and attached power cordsB Control Pendant 1 Enable/disable the BitRunner V2C Logic Cable 1 Connects the BitRunner V2 to the controllerD Ethernet Cable 1 Connects the BitRunner V2 to the control pendantE Grounding Cable 1 Attaches to spindle mount to ground the spindle1.2 Install a New Carbide Motion Board (v2.3 or earlier)If you have an older Carbide Motion board (2.3 or earlier), you should have purchased a new Carbide Motion PCB and enclosure with your BitRunner V2. Before setting up the BitRunner V2, you will need to install the new controller:1.Power off the machine.2.Disconnect the power and USB cables, and all of the motor cables and homing switches from theboard.3.Remove your old controller from the machine.4.Install the new controller. The USB and power ports face the back of the machine.5.Reconnect the motor, homing switch, power, and USB cables.1.3 Connect the BitRunner V2 to the ControllerThe BitRunner V2 is designed to lay flat on the ground near your work table and electrical outlet.The 6-pin male-to-female logic cable connects the BitRunner V2 to the Shapeoko controller. The male end of the cable plugs into the BitRunner V2 and the female end plugs into the controller.1.Plug the male end of the logic cable into the 6-pin female port on the top of the BitRunner V2. SeeFigure 2.a.The black plastic latch on the side of the connector faces RIGHT.b.Make sure the connector is fully seated. You will hear the latch click into place.Figure 21.Plug the cable’s female end into the 6-pin male BitRunner V2 connector protruding from the front-end of the controller. See Figure 3.a.The small triangular peg faces OUT (away from the rail).b.The connector fits tightly. Press in and down to get it to seat fully.Figure 31.4 Connect the BitRunner V2 to the Control PendantUse the flat black Ethernet cable to connect the BitRunner V2 to the control pendant. The two ends of the cable are interchangeable. See Figure 4.1.Plug one end of the Ethernet cable into the Ethernet jack on the control pendant.a.The clear latch and black strain-relief boot face up.b.Press firmly to fully seat the connector. You will hear the latch click into place.Figure 42.Plug the other end of the Ethernet cable into the jack on the top of the BitRunner V2. See Figure 5.a.The clear latch and black strain-relief boot face LEFT.b. Press firmly to fully seat the connector. You will hear the latch click into place.Figure 51.5 Connect the BitRunner V2 to the Router and Power1.Plug the spindle/router power cord into the short female power cable on the left side of theBitRunner V2.2.Plug the longer male power cable into a wall outlet.1.6 Attach the Grounding Cable to the Spindle Mount (Optional)To attach the grounding cable:1.Insert the banana plug into the round port on the top of the BitRunner V2. See Figure 6.Figure 6e an M5 screw to secure the ring terminal end of the grounding cable to one of the two M5 holeson the left side of the spindle mount. See Figure 7.e a couple of zip ties to secure the grounding cable. Make sure the cable is secured where it willnot get in the way of the machine’s movements.Figure 71.7 Upgrade Carbide MotionThe BitRunner V2 requires at least Carbide Motion 4.1.Check for the build number in the bottom-left corner of Carbide Motion. Build numbers higher than400 do not need to be upgraded.2.If you have an older version, download the most recent version of Carbide Motion from/carbidemotion/download and install it to your computer.Using the BitRunner V22.1 Enable/Disable the BitRunner V2The BitRunner V2 is enabled and disabled via the control pendant.To enable the BitRunner V2:1.Press the control pendant button to supply power to the router. The red button LED will turn ON. SeeFigure 8.Figure 8To disable the BitRunner V2:2.Press the control pendant button again to cut power to the router. The button LED will turn OFF.2.2 Install an End Mill1.Press the control pendant button to disable the BitRunner V2 (button LED will be OFF).2.Flip the power switch on the router to the OFF position.3.Install the end mill.2.3 Run the Project G-code1.Flip the power switch on the router to the ON position.2.Press the button on the control pendant to enable the BitRunner V2.3.Load the G-code (.nc file) in Carbide Motion.The G-code (or absence thereof) determines when BitRunner V2 cuts or supplies power to the router. If there is no G-code/.nc file being executed in Carbide Motion, then no power is supplied to the router. TheG-code also triggers alert boxes to open in Carbide Motion which let you know when it’s time to change the end mill, what RPM to set the spindle to, etc.When G-code is executed in Carbide Motion, specific commands will determine if power is on or off: •An M3 S command of 1000 or greater (1000 is the RPM) automatically turns the router on. M3 S2800 is an example M3 S command. Alternately, you might see commands written like this: M3S2800.•An M5 command turns the router off.•An M6 command indicates a tool change.2.4 Perform Tool Changes1.When the G-code reaches a tool-change command (M6) Carbide Motion will pause the job, cutpower to the router, and alert you that it’s time to change the tool.2.Press the control pendant button to disable the BitRunner V2 (button LED will turn off).3.Flip the power switch on the router to the OFF position.4.Change the end mill.5.Flip the power switch on the router to the ON position.6.Press the control pendant button again to re-enable the BitRunner V2 (button LED will turn on).7.In Carbide Motion, click the Resume button to resume cutting. Carbide Motion will continue cuttinguntil it’s time to perform another tool change, load the next G-code file, or until the project is done.See Figure 9.Figure 9Troubleshooting and Maintenance 3.1 Troubleshooting Guide3.2 MaintenanceCheck the top of the BitRunner V2 for dust accumulation periodically, and vacuum when necessary.3.3 Replacing the FuseThe fuse may have blown if you know the G-code is good and the control pendant LED still lights up, but the BitRunner V2 has stopped working.1.Unplug the BitRunner V2 from the power source and unplug all cables on the top of the device.e a 2.5mm hex key to remove the four FHS securing the back panel.e a 2.5 mm hex key to remove the six BHCS securing the metal EMI shield.

Encounter使用入门教程本教程介绍一下自动布局布线工具Encounter的使用知识，开始以一个简单的十进制计数器版图的自动实现为例子，之后介绍包含block模块的复杂的版图自动实现。
在Designer Compiler使用入门教程中，笔者设计了一个十进制计数器，并经过Design Compiler对其进行综合后获得了门级综合网表文件counter.sv以及约束文件counter.sdc，根据这两个文件，我们就可以使用SOC Encounter实现十进制计数器的物理版图设计了。
首先，我们要准备使用Encounter进行版图自动设计时所需要的数据：时序库文件：fast.lib,slow.lib,tpz973gwc.lib,tpz973gbc.lib物理库文件：tsmc18_6lm_cic.lef,tpz973g_5lm_cic.lef,tsmc18_6lm_antenna_cic.lef 门级网表文件：pad_counter.sv时序约束文件：pad_counter.sdcIO位置放置文件：pad_counter.io //在设计导入Encounter中指定PAD的放置位置文件，不是必须文件还有其它一些文件在后面用到时进行介绍。
一、网表中添加PAD、编写IO Assignment File这里，pad_counter.sv是加入PAD后综合得到的门级网表。
工程项目中设计制作完成后的芯片要进行封装，PAD就是芯片在封装时连接封装引线的地方。
一般信号输入/输出PAD即I/O PAD要在综合前添加进入网表中，电源电压PAD 可以在综合时添加也可以在综合后添加。
接下来就先介绍一下如何在网表中加入PAD，其实给网表加入PAD就是一般的module例化，和Verilog中一般的module 模块例化是一样的。
这里介绍在综合时给设计中加入I/O PAD。
十进制计数器的Verilog源程序如下：module Cnt10(reset_n,clk,in_ena,cnt,carry_ena);input clk;input reset_n;input in_ena;output [3:0] cnt;output carry_ena;reg [3:0] cnt;reg carry_ena;always @(posedge clk or negedge reset_n)beginif(!reset_n)cnt<=4'b0;else if(in_ena && cnt==4'd10)cnt<=4'b0;else if(in_ena && cnt<4'd10)cnt<=cnt+1'b1;endalways @(posedge clk or negedge reset_n)beginif(!reset_n)carry_ena<=1'b0;else if(in_ena && cnt==4'd10)carry_ena<=1'b1;elsecarry_ena<=1'b0;endendmodule加入PAD后的十进制计数器Verilog网表如下：module Cnt10_PAD(reset_n,clk,in_ena,cnt,carry_ena); //顶层模块input reset_n;input clk;input in_ena;output [3:0] cnt;output carry_ena;wire top_clk,top_reset,top_in_ena;wire top_carry_ena;wire [3:0] top_cnt;Cnt10CNT10(.reset_n(top_reset),.clk(top_clk),.in_ena(top_in_ena),.cnt(top_cnt),.carry_ena (top_carry_ena)); //这里是对Cnt10 module的例化//下面是I/O PAD module的例化PDIDGZ PAD_CLK(.PAD(clk),.C(top_clk));PDIDGZ PAD_RESET(.PAD(reset_n),.C(top_reset));PDIDGZ PAD_IN_ENA(.PAD(in_ena),.C(top_in_ena));PDO02CDG PAD_CARRY_ENA(.I(top_carry_ena),.PAD(carry_ena));PDO02CDG PAD_CNT_0(.I(top_cnt[0]),.PAD(cnt[0]));PDO02CDG PAD_CNT_1(.I(top_cnt[1]),.PAD(cnt[1]));PDO02CDG PAD_CNT_2(.I(top_cnt[2]),.PAD(cnt[2]));PDO02CDG PAD_CNT_3(.I(top_cnt[3]),.PAD(cnt[3]));endmodule说明：关于PAD如何例化，首先要查看厂家提供的工艺库中的关于PAD的verilog 文件，如本例子中使用tsmc18工艺库，描述PAD的verilog文件为tpz973g.v，这个文件是PAD文件的verilog描述，包括输入输出的端口等信息。
