1.5i Virtex PAR - Router is routing backbone net to IOB CLK pins incorrectly.

描述

The router is routing a backbone clock net to the IOB CLK pins incorrectly. It is routing off of vertical long lines instead of the backbone horizontal. This increases the skew to the IOBs by about 3.0ns or 50% of the total delay.

解决方案

A fix for this problem is included in the 1.5i Service Pack 1. For details
