3.1i Virtex PAR- PAR hangs during PWR/GND routing.
Keywords: Virtex, par, hangs, long time, PWR/GND,
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.
