14.x Virtex-7 - Design does not meet timing on Virtex-7 while design meets timing on Virtex-6 device

Description

I have a design that does not meet timing in a Virtex-7 device while the same design does meet timing on a Virtex-6 device.

How can I meet timing on the Virtex-7 device.

Solution

You cannot compare apples to apples between a Virtex-6 and Virtex-7 devices. They will have completely different timing numbers.

Virtex-7 FPGAis not in production and so the timing numbers will change.

In this case, by running some smartxplorer runs, we were able to find a run that actually met timing on the Virtex-7 device.
