Viewing Classes in Simvision

DylanC

Hello all,

I've just started creating a more robust test bench structure using classes.  I've never tried to use classes in verification before and so I'm having some trouble understanding how to view them in Simvision.

I've created a simple testbench with various classes for running the tests.  I can see the classes in Simvision waveform window but there is no data for them.  I do have data for the DUT signals and the testbench seems to be working correctly.  

Is there something I need to do to make sure the data for classes is recorded?  I'm using the $shm_probe to create the database but I don't see a switch for collecting class data.  

Thank you for any assistance.  I'm pretty new to Simvision so I'm probably missing a lot.

  • Add '-dynamic' to your 'probe' command. I typically have 'probe -create -all -depth all -dynamic'.

    Side node: I don't know what '$shm_probe' does, but it seems like it's connected to probing. You can replace this system task call with simulator TCL commands. Look for 'database' and 'probe' in 'cdnshelp'.
