[Cadence Virtuoso] matching schematic transistors with interdigitated layout counterparts

calbear2009

Hi,

In Cadence Virtuoso/Composer, I am trying to match multiple transistors devices in my schematic to interdigitated transistors in layout.

However, Virtuoso seems to have a problem mapping many schematic devices to a single cell in layout. How do I do this? This would be crucial for LVS, and I believe the interdigitated fingers for matching transistors is a common practice. Thanks a lot in advance!

  • Thanks for the reply.

    I am using Virtuoso Layout Editor 5.10.41...

    In this version, there is no 'Define Device Correspondence' in the 'Connectivity' menu,

    though there is a 'Device Correspondence' in the 'Create' menu.

    I can map one schematic instance to multiple layout instances here, but cadence won't allow

    me to do vice versa (dragging will not select multiple schematic instances). Any help would be great.Thanks!
