How to probe and view the variable wave in class?

archive

Hi,

It's happy to know IUS61 is released and have more debug feature.
I have tried the new simvision and found I cannot probe and view the variables wave in class.
Shall I add any particular command to probe it?

Probe command I use now:
database -open -shm -into waves.shm waves -default
probe -create -database waves top -all -depth all -mem -functions -tasks

Best regards,
Davy

  • Hi Davy,
          As of now tools don't support this. but interestingly Specman (now part of CDN) has been supporting it nicely for half-a-decade atleast! The idea was simple - use a dummy verilog/vhdl stub module/entity and pass on the dynamic values to static world as and when needed. The idea can be related to "callback" method that we demonstrated in our last year SNUG paper with VMM for FIFO. We used a dummy vitural interface named "debug_if" and got similar result.

    Maybe that can help you here for now! I wonder why CDN shall not leverage on Specman's mechanism for this, maybe in pipeline.
