pPar not works for intiger CDF parameters

Sarvani

 Hi all,

        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.

thankyou,

sarvani

  • Sarvani,

    It's hard to tell - it rather depends on whether the PDK has other things that depend on the parameters being integers. For example, there may be pcells which require the parameters to be integer (although that generally works OK because the parameters get cast to the right type), but I wouldn't like to say what the impact would be.

    There may be CDF callbacks which also assume the values are a specific type.

    Best would be to contact the foundry and ask them.You could also talk to customer support to discuss this in more detail with information as to which foundry you're using.

    Andrew.
