11.1 Virtex-5 MAP Known Issues - Incorrect optimization of latch with Gate driven by constant "1" but GE driven by active signal

描述

I have a latch in my design with G constantly high and an active signal on D. It has been optimized away so as to pass through the D signal despite the fact that GE is active. Is this optimization problem a known issue?

解决方案

This latch optimization issue is scheduled to be fixed in ISE 11.2.
