4.1i Virtex-II PAR - The placer crashes during the Clustering phase

Description

Keywords: clustering, phase, placer, crash

Urgency: Standard

General Description:
PAR crashes during the clustering phase of placement, freezing with a message similar to the following:

"Starting clustering phase. REAL time: 1 mins 37 secs."

(The problem was found to be related to unusually long component names.)

Solution

1

This problem is fixed in the latest 4.1i Service Pack, available at:
http://support.xilinx.com/support/techsup/sw_updates.
The first service pack containing the fix is 4.1i Service Pack 3.

2

A work around for this problem is to disable the clustering phase by setting the following environment variable:

set XIL_PAR_DO_CLUSTERING=2 (PCs)
setenv XIL_PAR_DO_CLUSTERING 2 (Work Stations)
