LogiCORE IP Ethernet AVB Endpoint v3.1 - Timing errors are occasionally seen when targeting Spartan-3 devices

描述

When I use the Ethernet AVB Endpoint v3.1 core and target a Spartan-3 device, the following timing constraint occasionally produces timing errors similar to the following:

TS_rtc_clock = PERIOD TIMEGRP "rtc_clock" 8 ns HIGH 50%;

解决方案

Running the implement tools again with a different cost table usually resolves this issue.
