Parameterization feature of ADE-XL does not work with Schematic Pcells

MFahmy

Hello, 

I am using  ICADV12.3-64b.500.17 

and I am trying to parametrize a design using the variables and parameters window in ADE-XL, and I am facing two different issues

I noticed that sweeping some parameters simply didn't work, by investigating the netlist I saw that although the swept parameters are set correctly at the begining of the netlist it is not passed to the device instant, in my case this problem was specific to schematic Pcells (ex. a Pcell which generates stacked devices) , so when sweeping the parameter number_of_series_devices in the PCell the structure of the underlying schematic needs to be re-evaluated but this is not happening 

additionally, I noticed in general that any parameter which is modified in the parent schematic Pcell is not passed to the underlying Pcell even if it is not affecting the structure 

Thanks

    Hi Fahmy,

    This is a known limitation. The issue is that the way we parameterise the design is done in a way to avoid having to re-netlist the design hierarchy, and then it only needs parameter value changes in the netlist. With the situation you describe, that will not work.

    If you need this, you should contact customer support. I believe there's an existing enhancement request (I didn't check to look up the CCR number).

    Regards,

    Andrew.
