The !netext Command: Batch Physical Net Extraction

Syntax: !netext arguments...
PRELIMINARY - This is the initial implementation of a new capability. Feedback and wish-lists from users is encouraged.

The !netext command performs identification and extraction of physical wire nets from a layout. There are a number of modes and features, but the final result is generally an OASIS file containing a top-level cell with the same name as the original top-level cell, which contains a subcell for every wire net. Each subcell contains all of the conductors that comprise the net, as if the original hierarchy were flat. This file can be used as a starting point for further analysis, such as parasitic extraction using a field solver.

The full operation is performed in three stages.
