Waveform of task in class?

I saw the same/similar post in comp.lang.verilog, here is my reply to that post>>

I don't use IUS, but going by other simulators, SV class dumping to
waveform is not something as easy as that of modules, hence this may
be not yet implemented feature. IMHO in many cases one can do without
it. As we speak I'm writing a paper on Advanced Debugging for SV
testbenches for SNUG India 2007. That talks about special approaches
for testbenches. Some key points:

1. It really helps if the environment is layered - be it VMM or AVM
etc. I don't know much about uRM except its name, hope it has similar
layered approach.
2. If #1 is true, then the "task in waveform" is required only for
"command transactor" or BFM layer. And there we do have a virtual
interface, simply add few extra debug signals to that interface and
update the class members to that interface. This approach is detailed
in our 2006 SJ SNUG paper as well.

3. Even for any class this approach #2 works as a workaround.
4. For higher level models, breakpoints, transaction tracking etc. is
important. We are looking at Verdi, command line debugger etc. for
this.

Hi Davy.

Firstly, you should really use a newer version of Incisive, the version you mention is so old I doubt it has much support for classes at all!

Secondly, because most of the activity inside class methods happens in zero time, putting the class variables into the waveform doesn't generally help you to understand the execution of the testbench. It's better to either single-step the simulation in the SimVision debug GUI and watch the code execute on the fly, or the best is to use the Indago Debug Analyzer tool which probes all your testbench activity and allows you to post-process debug the classes with reverse stepping back from the point of failure. It is a massive time-saver. Indago is only available in relatively recent version of Incisive, you'd want to be using 14.2 or later, and ideally 15.2.

Your local Cadence AE should be able to help you with that. If you're not sure who your local contact is, drop me a private message with your corporate email and location, and I'll get someone to get in touch.
