Synopsys正式推出HAPS

Intel PSG为什么要做可编程加速卡？单祥茹【期刊名称】《中国电子商情·基础电子》【年(卷),期】2018(000)005【总页数】2页(P23-24)【作者】单祥茹【作者单位】【正文语种】中文Intel PSG的前身是全球著名的FPGA厂商Altera公司，2015年底被Intel收购。

FPGA是一个高技术门槛的行业，即便已经成为Intel可编程解决方案事业部，它的一举一动仍然引人关注。

在今年4月份的北京媒体见面会上，Intel PSG亚太区市场拓展经理刘斌不仅介绍了FPGA在数据中心的主流应用，更是带来一个重要信息：除了FPGA芯片，Intel PSG还将向市场提供采用Arria 10 GX FPGA的Intel可编程加速卡（Intel PAC）。

同时部署面向Intel至强CPU和FPGA加速堆栈，为软件开发人员提供强大支持。

此举意味着，原始设备制造商 (OEM) 在其服务器系列中可以采用Intel FPGA加速。

这也是由Intel自己提供的可编程加速卡在现代数据中心中的首次重要使用。

事实上，在Intel推出该款加速卡之前，FPGA已经在服务器加速中获得应用，那么，Intel 为什么又要推出这样一款加速卡呢？刘斌表示：“Intel做这件事是认真的，主要基于三个方面的考虑。

第一，要根据Intel特定的产品质量标准来约束加速卡的产品质量。

也就是说加速卡是Intel品牌之下的一款产品，它能确保合作伙伴在服务器中做加速卡验证时，享有与Intel芯片同等的质量标准。

第二，服务器提供商希望有一个中立的机构提供用于加速的产品，以利于他们做出合理的选择。

实际上Intel本身在计算领域的地位决定了我们是提供FPGA加速卡的最佳选择。

第三，加速卡的问世还反映了Intel在FPGA领域的投资策略，是非常重要的一步。

如果没有加速卡，单纯的FPGA芯片很难在加速领域推广部署。

”与过去单纯的FPGA解决方案不同，这一次在FPGA加速卡问世的同时，Intel还同步推出了加速堆栈，提供标准的应用访问接口。

VHDL语言编程用什么编译软件_需要看哪方面的书籍VHDL 的英文全名是VHSIC Hardware Description Language（VHSIC硬件描述语言）。

VHSIC是Very High Speed Integrated Circuit的缩写，是20世纪80年代在美国国防部的资助下始创的，并最终导致了VHDL语言的出现。

本文主要介绍了VHDL语言编程用什么编译软件以及学习VHDL语言需要看哪方面的书籍，最后还阐述了学习VHDL 语言应注意的几个问题盘点。

VHDL语言特点VHDL语言能够成为标准化的硬件描述语言并获得广泛应用，它自身必然具有很多其他硬件描述语言所不具备的优点。

归纳起来，VHDL语言主要具有以下优点：（1）VHDL语言功能强大，设计方式多样VHDL语言具有强大的语言结构，只需采用简单明确的VHDL语言程序就可以描述十分复杂的硬件电路。

同时，它还具有多层次的电路设计描述功能。

此外，VHDL语言能够同时支持同步电路、异步电路和随机电路的设计实现，这是其他硬件描述语言所不能比拟的。

VHDL语言设计方法灵活多样，既支持自顶向下的设计方式，也支持自底向上的设计方法；既支持模块化设计方法，也支持层次化设计方法。

（2）VHDL语言具有强大的硬件描述能力VHDL语言具有多层次的电路设计描述功能，既可描述系统级电路，也可以描述门级电路；描述方式既可以采用行为描述、寄存器传输描述或者结构描述，也可以采用三者的混合描述方式。

同时，VHDL语言也支持惯性延迟和传输延迟，这样可以准确地建立硬件电路的模型。

VHDL语言的强大描述能力还体现在它具有丰富的数据类型。

VHDL语言既支持标准定义的数据类型，也支持用户定义的数据类型，这样便会给硬件描述带来较大的自由度。

（3）VHDL语言具有很强的移植能力VHDL语言很强的移植能力主要体现在：对于同一个硬件电路的VHDL语言描述，它可以从一个模拟器移植到另一个模拟器上、从一个综合器移植到另一个综合器上或者从一个工作平台移植到另一个工作平台上去执行。

The breakpoint at line 63 triggers on the positive edge of the sample clock when the current_state signal has the value s_TWO .Now that you have an active trigger condition, arm the IICE triggercircuits on the FPGA device by clicking the Run icon in the menu bar. Clicking on the Run icon downloads the trigger information to theIICE. When the trigger occurs, the sampled data is transferred back to the debugger. The small arrow to the left of the breakpoint icon indicates which breakpoint triggered (identifying which breakpoint triggered is important when multiple breakpoints are active).The Cycle display in the middle of the menu bar shows the value zero where the trigger occurred. By clicking on the up-down arrows on the right, you can increase or decrease the cycle count to show values immediately before orafter the trigger point. Early Middle Late CycleYou can change where the trigger point is in the buffer by selecting one of the Early, Middle, or Late icons to the left of the cycle counter and again clicking the Run icon. The trigger location changes the next time the IICE triggers. Triggering on a WatchpointYou can also trigger on a watchpoint that is specified on any sampled signal.The Watchpoint Setup dialog box accepts any legal VHDL (or Verilog) expression that evaluates to a constant.To set a simple watchpoint:1.Click on the current_state signal2.Select Set trigger expressions from the popup menu3.In the first (left) field, enter s_THREE and c lick OKClick the Run icon. When signal current_state reaches the value s_THREE,the IICE triggers.Note:Because randomly generated data is applied, the trigger watch-point (s_THREE) may not reach its intended value. Click the adja-cent STOP icon if triggering does not occur within a few seconds.Using the Cycle data display controller, you can now browse back and forth through the debugger data buffer to view the design activity.Cycle data display controllerTutorialIdentify Microsemi Edition Quick Tutorial © 2015 Synopsys, Inc.March 201521Using the Complex CounterThe default settings for the complex counter mode (events with a value of 1) effectively disable the counter. To use the complex counter to wait for a breakpoint and/or watchpoint trigger event and then to count a specified number of cycles before triggering the sample buffer:1.Set the counter mode to cycles and the counter value to a value greaterthan 1 (note that you must have previously enabled Complex countertriggering on the IICE Controller tab in the Identify instrumentor).2.Change the watchpoint of signal current_state to s_TWO .3.Click the Run icon and wait for the data to download.The value at time zero will be updated with the sample data after the specified number of cycles has occurred as shown in the following figure.Note:Because randomly generated data is applied to all instrumented nodes, the results displayed do not reflect actual design plex counter settingsTutorial© 2015 Synopsys, Inc.Identify Microsemi Edition Quick Tutorial 22March 2015Generating WaveformsDisplay the debug data by clicking the Open Waveform Display icon in the menu bar.
