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,

    You can only use pPar() on CDF parameters of type string, which have parseAsCEL set to Yes. You can only use expressions (including operators and math functions) on string fields, and if they are going to be interpreted, it has to know it should be treated as a component expression language (a.k.a. Analog Expression Language) expression. If the CDF parameter is defined as an int or a float, you can only set the value to be an int or a float; an expression would not be an int or a float and so it cannot be used.

    It's quite unusual for foundry PDKs to be using int or float parameters - it sounds as if something is incorrect with the setup and it hasn't been designed with ADE in mind.

    Regards,

    Andrew.
