simvision: how to add all signals in design to waves

SysTom

Hello,  What are the fewest commands to add all signals in design to waveform viewer?  Thanks, SysTom

  • Hi Thomas,

    That is an interesting challenge. ;-)

    Please try the following SimVision commands (assuming you have the Design Browser and Waveform windows opened):

    browser select deep <top_scope_name>
    waveform add -selected


    Please be careful about adding too many signals into the waveform. That can introduce performance issues.

    Good luck...

  • Hi Doug,

    Thank you for your feedback. Yes, that seems to work. I also found I could do this:

    database -open waves -into waves.shm -statement -default
    scope -set {top}
    probe -create -all -depth all -waveform

    Both methods added a much more significant simulation burden than I had anticipated - even with my relatively small design/TB.

    Thanks again,
    Tom
  • Hi Tom,

    Yes, enabling statement trace recording (database -statement) will definitely significantly degrade simulation performance. I would avoid doing that if at all possible.

    I would also suggest probing depth to "to_cells" level instead of "all", unless you really need to probe within cells.

    Thanks.

  • Hi Doug,

    Thanks for the tip: I tried to_cells. In my case it was quicker to load the waves but performance was still degraded somewhat (less than 'all'). I'll look into a way to cherry-pick was I need a bit better.
