2.1i Virtex Map - Inversion between MUXCY and Flop is dropped/


Keywords: Inversion, Inverted, Carry, MUXCY, Flop, Register

Urgency: Standard

General Description:
A case has been seen where an inversion was being dropped
between a MUXCY and a Flop in the same slice. The mapper
attempted to use the XORCY to implement the inversion, but
incorrectly drove the other pin with a "0" instead of a "1".
