Change parameters in pcDefinePCell code body

RVERP

Hi, I have a normal pcell that you can give certain parameters.  I want to check in this pcell if certain parameters are between a min and max value, and the reset the parameter to this value.  How is this done?

 

For now i tried a if else statement.
So I have parameter l, in the code body i check

if( l<minL then l = minL)

If I create an instance of this pcell, and enter a value lower as minL, this results in a pcell with correct l, only the value I initial entered is still visible in the instance parameters. 

Can I change this?

 

Thanks,

Rik

     Hi Rik,

    This is a case where CDF callbacks can be used to good effect - the PCell parameter would have an associated CDF parameter, and this parameter would have a callback so that when the value is entered/changed on a form (Edit Object Properties, Add Instance) the value is checked within the boundaries that you set up; the CDF callback can modify (e.g. reset to min or max) the value to provide feedback to the user (along with a printed statement in the CIW, perhaps?)

    Search for CDF callbacks if you need more help, or post follow-on questions here.

    Hope this helps!

    Regards,

    Lawrence.
