4.1i Virtex MAP - MAP crashes after printing "Using target part "v600fg676-4".

Description

Keywords: BUFG, load, Virtex, crash, clock, buffer

Urgency: Standard

General Description:
A Virtex design crashes in the MAP phase after printing the message "Using target part "v600fg676-4".

Solution

The problem is related to the fact that there was a BUFG in the design with no load net attached. A CR has been logged and is under investigation.

Meanwhile, a work-around is to either remove the unused BUFG, or to add a load to the output.
