Getting the Signal Waveforms into the Waveform Window with Xrun Command

anurans

Dear All,

In Simvision, I want to load the saved signal names (not historical database values) of a design, when running a new simulation. Usually what I do is : 

xrun -clean ASYNC_FILTER.v  tb_async_fb.v  -v llk65nmmvbbr_sdf30.v -access +rwc -mess -timescale 1ns/1ps -gui

and then in the gui, I load the signals from an .svwf file !

I want to do this in a single xrun command, so I tried : 

1. xrun -clean ASYNC_FILTER.v  tb_async_fb.v  -v llk65nmmvbbr_sdf30.v -access +rwc -mess -timescale 1ns/1ps -gui -simvisargs "waveform loadsignals -using Waveform Window 1 FB1.svwf" and I always get an error.

2. xrun -clean ASYNC_FILTER.v tb_async_fb.v -v llk65nmmvbbr_sdf30.v -input load_wave.tcl -access +rwc -mess -timescale 1ns/1ps -gui and the load_wave.tcl has : 

waveform loadsignals -using "Waveform 2" FB1.svwf

This also gives errors. How can I get this solved ?

Thanks

  • Hi Anuran.

    The -simvisargs passes command-line switches to the simvision binary, not Tcl commands. You can send Tcl commands to SimVision from the Xcelium Tcl prompt, much like you tried in your 2nd trial, however the bit you missed is that Xcelium and Simvision have separate Tcl interpreters, so you need to prefix your "waveform" command with a special command to send the command over to SimVision: here's a pointer to the Xcelium Tcl command reference.

    Your load_wave.tcl needs to contain:
    simvision -submit waveform loadsignals -using "Waveform 2" FB1.svwf

    Hi, thanks for the input. However whatever I put within double quotes as the WW name (without/with spaces), I get the bad waveform window name error.

    I'm going to guess that by the time the waveform command executes, you haven't got a waveform window open yet.

    Try adding this command ahead of the waveform loadsignals one in your Tcl:

    simvision -submit waveform new -reuse -name Waveforms

    simvision -submit waveform loadsignals -using Waveforms FB1.svwf

    Note that if you start to need a lot of simvision Tcl commands it might be better to put them in their own file and pass them to Simvision as one file, perhaps with "xrun -simvisargs '-input mysimvis.tcl'" or from Xcelium's Tcl prompt using "simvision -input mysimvis.tcl"

    Thanks a lot, that solves the problem.
