5.1i Project Navigator - "Placer Effort Level" and "Router Effort Level" options are not separately available in the MPPR flow

Description

Keywords: MPPR, re-entrant, routing, Placer, Router, Effort level, PAR, -pl, -rl, Project Navigator, ProjNav, ISE

Urgency: Standard

General Description:
For best results, 5.1i MPPR should be run with the Placer Effort level (-pl) set to 5 and the Router Effort level (-rl) set to 1 or 2. However, in Project Navigator, "-pl" and "-rl" are not separately available for MPPR.

(Setting -rl to 1 or 2 for MPPR will significantly reduce run times. This MPPR feature is available through the 5.1i command line.)

Solution

This problem is fixed in the latest 5.1i Service Pack, available at:
http://support.xilinx.com/support/techsup/sw_updates
The first service pack containing the fix is 5.1i Service Pack 1.
