Parameterize number of iterated instances

The Setlaz

Hi,


I'm using IC12 ISR9 and I'm looking for a way of making the number of iterated instances (and its associated bus name) to take a variable instead of an integer.

eg: put N resistors in series using: instance R<N:0>  connected to "Rp, RNext<N-1:0>" on one side, and "RNext<N-1:0>,Rn"  on the other side and being able to set and/or sweep parameter N.

 

I couldn't find an easy way to do that. Is it even possible ? Or is there any way/workaround to do something similar ?

 

Thanks,

Damien

PS: I picked a resistor, but the application would be for stacking transistors as the maximum gate length gets smaller and smaller as we go into more advanced process nodes)

  • Damien,

    There is no support for this, either in the OA database or the tool. Typically for series connected (or stacked) resistors or transistors this is done with a schematic pcell. For transistors, for some advanced node models, there may be an instance parameter that allows specifying of series connected device (depends on the model used, I think).

    Regards,

    Andrew.
