Virtex-4 GT11 SmartModel Simulation - TX serial output skewed in SimPrims Timing simulation

Description

In 9.1i design tools and earlier, when using multiple GT11s configured for Low-latency buffered mode with channel deskew, a significant skew of about 20 UI can sometimes be seen between the TX serial pins of different GT11s in timing simulation.

Solution

A work-around is currently being investigated for this issue.
