3.1i Virtex PAR- PAR hangs during PWR/GND routing.

Description

Keywords: Virtex, par, hangs, long time, PWR/GND,

Urgency: hot

General Description
A case has been seen where PAR hangs during PWR/GND routing.
This was found to occur when a PWR/GND net has to "shove" itself
in order to open up a routing resource. This is most likely to occur on
dense designs with very large PWR/GND nets.
