Waveform files

[Abel Alaniz]

Is there any command line options to dump a wave file into our output directory.    

Thanks

What simulator?

[David Stanford]

use the -r option when calling runSVUnit and pass it a .do file that contains log -r /*.

log_all_to_wlf.do file contents:
log -r /*

then on the command line:
runSVUnit -s modelsim -r “-do log_all_to_wlf.do”

Hi Jerry,

My simulator is VCS.    So this is a simulator option and not an SVUnit option.

Thanks,

Abel

Hi Abel:

It is still a SVUnit option to pass switches to the simulator, so David Stanford is correct that you will be using SVUnit's -r option.  I believe that for every simulator switch you add it needs to have it's own -r switch for svunit.

Sorry for taking so long to reply Abel... Unfortunately I currently don't have access to Synopsys simulators or licenses, so I can't verify the exact switches needed to dump wave files.  Perhaps one of the other users on this list can supply the correct switches for vcs?.

With Questa, I use: runSVUnit -s questa -r -voptargs=+acc -r -gui

Then when the GUI comes up, first do a "log -r /*" to make sure everything is logged correctly in the resulting .wlf file.  Or you can pass in a dofile with that command as David's email shows. Leave off the -gui switch and it will run in batch by default.

With Cadence, I believe it's simply adding a -r +gui to SVUnit if you want the gui, then add the specific switches you need to direct the output to either Verdi or SimVision waveform DBs.  Remember each simulator switch requires a separate -r switch for SVUnit.
