Did you know that you can wave Specman objects in IES-XL *and* also save the wave setup for automatically restarting the simulation? If not, this tech tip is for you! Here is the process:
Step 0 – Once you are happy with your waveform setup, don’t forget the basic step of saving your mix of RTL signals and Specman fields/events using the [File] → [Save] command script menu item in SimVision.
Step 1 - After adding all the desired fields, signals, and events to the waveform, use the “write wave to” Specman command to create an ecom file named <filename>.ecom with all the wave commands Specman needs to recreate your trace setup:
> write wave to <filename>
Step 2 - When you “source” this ecom file in a new simulation, either using “sn @<filename>” in IES-XL or “@<filename>” in stand-alone Specman, the fields and events will be added to a new waveform window.
Important: the environment must be generated (by running the test command) before the trace ecom can be applied. In other words, in the new simulation load the ecom file before sourcing the saved command script
Step 3 - To automate this for follow-on simulations (where “sn_wave” is the <filename> you specified in step 1 above):
% irun -input nc_in.tcl
Where inside the file “nc_in.tcl” you have:
simvision input simvision.svcf

This is actually a known bug (see CCMPR00739590), which has been fixed and merged into the latest branch.
It should be available on the upcoming 8.2 S8 and 9.2 S6.
Please let us know if you have additional questions.
I am using IES 9.2 and try to add event and uint variable into waveform. But it only work fine for the first time. If I want to reload the e code and rerun the simulation. The waveform become very ugly. All the event and uint variables display far behind the real time it should be trigged.
Such the simulation finished at 1000ns, the first event may only changed on the waveform at 500ns.
