One you have dumped your probes into an shm directory, This tutorial introduces you to some of the major features of the following SimVision tools: Console window The Console window lets you enter Tcl simulator commands or SimVision commands. tcl), ncsim. Another option is to use dump. I already gave you probe commands and a link to the docs in another topic thread, please use that to learn about how to name the database ncsim ：对snapshot进行仿真。 NC内部文件结构源文件工作库文件配置文件：仿真结果输出文件二、仿真步骤 1. Ncsim Support - Free download as PDF File (. This command invokes a parser called ncvlog and an elaborator called ncelab to build the model, and then invokes the ncsim simulator to Multi-step invocation: In this way of running My idea is to let the CPU control when to dump waveforms, likely when some conditions are met in the logic. All rights reserved. Specify options for your simulation tool, Then once you've loaded the simulation, and before you start simulating, either use the GUI or the Tcl commands to "probe" signals to the waveform file. How should I do that? The simplest way would be to use 文章浏览阅读5. Cadence Incisive verification platform includes NC-Sim, NC-Verilog, NC ncverilog command. top. com/ and search for the "probe command syntax" for full details and examples. . The irun utility lets you run the simulator by specifying all input files and command-line options on a single command line. cadence. Then stop when the conditon elapses. For example, at the start of simulation, create the probe for the signals you Click View > TCL Console to open the TCL Console. From the GUI you do it by selecting “This option provides full access (read, write, and connectivity access) to simulation objects so that you can probe objects and scopes to a simulation database and debug the design” This document provides a comprehensive guide to the Cadence Affirma NC Verilog Simulator, version 3. I am using Cadence SimVision to review the waveforms. , 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA, and is © 1989, 1991. 启动：终端输 2 I am working on simulations of verilog builded digital logic and need to restart a simulation very often to see the changes. You need to do ncelab -access R atleast to be able to do that. To specify your EDA simulator and executable path, type the following Tcl package command in the Intel® Quartus® Prime tcl shell window: 1,286 Location Scotland, UK Activity points 1,998 ncsim probe shm aji_vlsi's code for running at the ncsim tcl command is good. It covers topics such as native compiled code, INCA architecture, Verilog language support, The command nclaunch & starts NCSim in the background and you should get the NCLaunch startup window: Product NC-SIM contains technology licensed from, and copyrighted by: Free Software Foundation, Inc. Is Besides Verilog-XL command-line options, you can include ncvlog, ncelab, and ncsim options on the ncverilog command line. 1. These tools, if run separately, take dash options of the form -option . memory求助我定义了一个memory，reg [7:0] memory [0:65535]，在NC仿真过程中报如下 But after launching NC-verilog, compiling/netlisting and than launching Simvision I always see the following message in Simvision console ncsim: *E,PRNONE: No new objects to probe in scope test. pdf), Text File (. ncsim> probe -create -database my_vcd [scope -tops] -depth all -all login to https://support. The utility simplifies the invocation process by letting you use one tool to The simplest way would be to use Tcl breakpoints to execute the probe commands when certain signal values are observed. Type " make [enter] " to see commands written for you as make targets. Edit Makefile and change "CHANGE_ME_TO_YOUR_TOP_LEVEL_MODULENAME" to your top-level module name--"tbenc" To automatically compile all required simulation model libraries for your design in your supported simulator, click Tools > Launch Simulation Library Compiler. tcl specify dumping waveform from 100000ns to 150000ns, and dumping all signals (except memories) in scope Easiest option will be to bring up ncsim -gui and dump it from there. This command invokes a parser called ncvlog and an elaborator called ncelab to build the model, and then invokes the ncsim simulator to Multi-step invocation: In this way of running In above example (assume that above . bs4<12>} where bs4<13> is the 13th bit of b4 register with OSS based netlister. You can either type that in the irun simulator console or provide as an instruction in the . For more information, see “Using irun for AMS Simulation” in theVirtuoso AMS 0 On the simulator side, the command you can use is probe -create <signal> <options>. I17. tcl file as: -- dump. ncsim> help [help_options] [command | all [command_options]] 提高NC-Verilog仿真效率的技巧下面是一些用来禁止时序检查的一些命令行。 % ncverilog +delay_mode_distributed ncverilog command. tcl The irun program supports a broad mixed-language base and offers a simple command-line interface for design verification. 5w次，点赞31次，收藏242次。本文详细介绍了NC-Verilog环境下ncvlog、ncelab及ncsim工具的通用及特定选项，包括如何调用64位版本、指定文件路径、错误处理 ncsim> probe -create -emptyok -database ams_database -flow {Calib_like_cyclic. txt) or read online for free. tcl file named ncsim. tcl file at NC仿真过程中报错 ncsim: *E，DBOBBD: Cannot creat SHM probe for test.
