5.1i Virtex-II PAR - MPPR crashes during the placement of the second cost table run

Description

Keywords: second, 2nd, second, cost, table, Phase 9.19

Urgency: Hot

General Description:
Multi Pass Place and Route (MPPR) crashes during placement at Phase 9.19, when the second cost table is run.

Solution

This problem will be fixed in the 5.2i software, which will be available in February, 2003.

Meanwhile, you can work around this problem by setting the following environment variable:

PC:
set XIL_PAR_NO_DO_FDCOPT=1

Workstation:
setenv XIL_PAR_NO_DO_FDCOPT 1

Setting this variable disables the algorithm causing the failure. This should not affect results significantly.
