General Description: TRCE reports large delays for specific longlines

in the 4000XV devices.

解决方案

In the 1.5i speed files for the XV devices there is an incorrect parameter

value. This causes the delays associated with specific longlines to have

the incorrect delay.

This is can be resolved by installing the latest speed file updates. They

are available on the Xilinx FTP Site:
