6.1i Timing Analyzer/TRACE - Positive non-zero hold times are reported for Virtex-E devices in the data sheet section

描述

General Description:

When I run my Virtex-E design through the timing tools, I notice a positive hold time reported in the data sheet section of the timing report. Is this correct, or should I believe the Guaranteed Values in the data sheet?

解决方案

In this case, the Guaranteed Values from the data sheet are correct.

This problem has been fixed in the latest 6.1i Service Pack, available at:

The first service pack containing the fix is 6.1i Service Pack 1.
