Can pPar pass cyclic's field value from parent?

Hi,

I'm trying to create a wrapper pcell which required to pass value from parent. Unfortunately i encounter some issue in passing down the value where the cdf field is cyclic with below message:

\w *WARNING* Effective CDF parameter 'LAYER', cell 'scv', library 'myTechLib',
\w >--Value is not one of the specified choices.

May i know is there a way to pPar from parent's value where field is cyclic?

Thanks in advance.

So do you mean the parameter on the parent is cyclic, or the parameter on the instance where that you are trying to set to be pPar("parent") is cyclic?

Hi Adres,
Is the instance where that i'm trying to set to be pPar("parent") is cyclic, at the primitive level. If this is the case, how can i pass down the pPar("parent") value?
Current my (urgly) workaround is add pPar("parent") as one of the choice in cyclic.

The only thing I can suggest is setting the property on the instance with SKILL. I don't know whether this will work properly during netlisting etc - I'll leave you to check that:

car(geGetSelSet())~>theCyclicProp="pPar(\"parent\")"

Where theCyclicProp is whatever the name of the cyclic property. That way you can probably get away without it being one of the choices...

Thanks Andrew,
Its works for netlist but not SDL.

I assume by SDL you mean layout XL? Anyway, it was worth a try...
