Is pPar works for all CDF parameters? I need to pass intiger numbers (like no. of fingers) from top level to bottem level in schematic. But when I enter pPar(NF) through edit object properties options then it doesn't work's. How can I get this intiger values to bottom level? Let me know if any other set up is needed.
If things are set up correctly, this should work. It's been possible to do this for many years (I was using such parameterization 20 years ago as a designer). I suggest you contact customer support so that we can look at your data to find out what's gone wrong- some PDKs don't allow parameterization because they use CDF callbacks to generate derived parameters, and those derived parameters might be used for LVS - but I can't tell that without seeing the data (personally I think this is a badly designed PDK if this is the case, but it happens).
