4.2i Virtex-II PRO, PAR - PAR crashes during the first placement pass and reports an arithmetic exception core dump

Description

Keywords: arithmetic, exception, crash, fails, placement, placer

Urgency: Standard

General Description:
PAR crashes during the first placement pass and reports an arithmetic exception core dump.

Solution

This problem is fixed in the 5.1i software, which is currently scheduled for release in September, 2002.

Meanwhile, you may work around the problem by setting the following environment variable, which switches to an alternative placement algorithm. The quality of the results should be comparable, but the runtime will be longer. (This variable works only for Virtex-II and Virtex-II Pro.)

Workstations:
setenv XIL_PAR_PLACE_SLOW 1

PCs:
set XIL_PAR_PLACE_SLOW=1
