extractVerifyUnimplementedInstTerms

layout extractVerifyUnimplementedInstTerms boolean { t | nil }

Description

Specifies that the connectivity extractor should consider instance terminals with pin shapes that are not extractable including instance terminals with no pin shapes at all.

The default is t. When set to nil, the extractor and the functions it serves ignore any instance terminal which has no pin shape or which has a pin shape on a layer that is not extractable. This allows Layout XL to extract based only on the extract layers defined in the technology file.

This environment variable is considered only when extractVerifyOpenViolations is switched on.
