3.1i Virtex MAP - MAP crashes due to conflicting LOC constraints.


Keywords: LOC, IOB, PAD, crash

Urgency: Standard

General Description:
A case has been seen where MAP crashed during the "Running directed packing..." phase. The
problem was due to the fact that multiple registers had been assigned the same LOC attribute,
which was an IOB location. This conflict apparently leads to the MAP failure, as the design runs
successfully when the conflict is removed.


This problem has already been fixed for the next major release (July, 2001). MAP correctly reports
the conflict with a pack error.
