​​​​Abstract
 

By default, Calibre will extract and tie the intrinsic capacitance of nets to a virtual ground "0".

In pursuit of high accuracy parasitic extraction, ground capacitance could be better represented as coupling to ground layers rather than a common node

In order to make Calibre PEX recognize the physical ground layers in your design and couple the intrinsics to the correct underneath ground, ground layers must be specified in a PEX GROUND LAYER SVRF statement

This Support Kit will help you understand how to use the PEX GROUND LAYER command and correctly handle designs with multiple ground layers

Estimated time to complete: 30 minutes
