AR# 3516

描述

Urgency: Hot

General Description:

The patched speed files for the XC4000EX that were available

on the Xilinx FTP site have erroneous values for the quad line

line resources (for M1.3 only). Immediately discontinue use of

these speed files. This problem is limited to the 4000EX, and

not the XL or E parts.

解决方案

The original speed files shipped on the M1.3 CD do not have

this problem. However, the best solution is to update to M1.4,

which does not have the problem.
