Orcad - EPLD Muncher returns a warning on Orcad OBUFT symbols


Keywords: EPLD, OBUFT, warning, Muncher

Urgency: Standard

General Description:
The XEPLD Muncher returns the following warning when I am using an OBUFT in Orcad:

pl111:[Warning]Component '<instance_name>/U2' does not drive anything and
is removed.


This warning can be safely ignored.

The OBUFT symbol has an inverter in the underlying schematic that is annotated as "U2".
This gets munched in the flow and generates the warning.

An extra buffer was added to the macro for Orcad simulation purposes, and this inverter is
only used in functional simulation.
