Changing Schematic Property Value in CIW Window

bjlanza

I had a way to change a schematic property value in the CIW window but I can't remember it.

Example:

A transistor device has the parameters of length and width.  These devices are set up with a range of allowed values.  I want to be able to use a value that is not in the range.  I have been able to achieve this by setting the value in the CIW.

  • If you know the property name (you might need to check the CDF for the component to find the property name), you can select the instance and then do:

    geGetSelSet()~>w="2u"

    That's if it was a property called w, and you're setting it to 2u. Whether this makes sense or not is dependent upon the PDK and whether there are CDF callbacks needed to set derived parameters which are used elsewhere in the flow, so proceed with caution. It also depends on what datatype the parameter is expecting, and so on.

    Regards,

    Thank you.  That is exactly what I was looking for.
