bsource Interpreted Label cdsParam() display

Update:

I've tried to play around with the opParamExprList parameter, and I've set up my init file to do the following:

let((CdfId)
CdfId = cdfCreateUserCellCDF(ddGetObj("mytechlib" "caplnmos"))
CdfId->simInfo = cdfGetBaseCellCDF(ddGetObj("mytechlib" "caplnmos"))->simInfo
CdfId->simInfo->spectre->opParamExprList='(("cap" "OP(mappedRoot(\".c1\") \"cap\")"))
CdfId->opPointLabelSet = "cap"
);let

This however does not seem to work.

2nd Update:

Now the above seems to work, after I've cleared the simulation directory. It could be that something I did wrong while fiddling with this prevented the solution from working.

I hope my journey of posts helps someone someday.

I didn't see your last post until after I'd put together a small example, which is using precisely the code you provided (I thought it looked OK, I just wanted to check). So in the attached (assuming I can get it to upload), there's a library "mytechlib" with a testbench inside which references the "caplnmos" component (which was copied from cap in analogLib, and then the CDF changed to have a default model of caplnmos). There's an ADE state which you can load an simulate and then annotate the DC operating point.

If you load "forum.il" (your code) and then do a Simulation->Netlist->Recreate, it should then work. The reason it probably didn't work for you was that you didn't force the netlist to be recreated. The opParamExprList info gets stored in the mapping directories when you netlist, and so if the CDF was changed after netlisting, it won't have an impact unless netlisting is done again (and if nothing changed in the schematic, you'll have to force a netlist change).

Also, if possible, I'd change the base CDF if you can, because otherwise it will get lost if somebody does a File->Refresh in the CIW (you're only changing the user CDF in your code).

Thanks a lot Andrew.

I did manage to get hold of your upload.

You are right about File->Refresh in the CIW that refreshes the base CDF. Would there be a way to safely attach a callback to the ddsHiRefresh() command? Most of the time I cannot open techfile cells in write mode.

Kind Regards,

Hi Tjaart,

No, there's no callback for this. The only option would be to replace the menu item in the CIW (and in the library manager), and that of course assumes that somebody doesn't call the SKILL function directly.
