9.1i Virtex-II PAR - Controlling placement of cascaded BUFGMUXs

描述

If there are more than eight BUFGMUXs and some of them are cascaded, the placer algorithms that handle BUFGMUX placement do not take into account the potential for a primary/secondary conflict due to the BUFGMUX load.

解决方案

In this case, the BUFGMUXs should be manually constrained so that no primary/secondary conflicts exist.
