Hi all,We all know that tasks in module can be viewed in simvision by add a "probe -tasks".But how to see waveform of task in class?BTW, I use IUS583.Best regards,Davy
I saw the same/similar post in comp.lang.verilog, here is my reply to that post>>Ajeetha, CVCwww.noveldv.comI don't use IUS, but going by other simulators, SV class dumping towaveform is not something as easy as that of modules, hence this maybe not yet implemented feature. IMHO in many cases one can do withoutit. As we speak I'm writing a paper on Advanced Debugging for SVtestbenches for SNUG India 2007. That talks about special approachesfor testbenches. Some key points:1. It really helps if the environment is layered - be it VMM or AVMetc. I don't know much about uRM except its name, hope it has similarlayered 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 virtualinterface, simply add few extra debug signals to that interface andupdate the class members to that interface. This approach is detailedin 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. isimportant. We are looking at Verdi, command line debugger etc. forthis.RegardsAjeetha, CVCwww.noveldv.com
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.
