Known Issue: 1.9.1
After updating to v1.9.1, the Endpoint takes longer to train in simulation, sometimes by as much as 350 us.
The added simulation time results from a fix for the issue described in (Xilinx Answer 31845). Depending on the chosen reference clock, training can take 100-350 us longer than in previous versions of the core. Functionality of the core is not affected. This has no negative impact on hardware operation.
A patch for this has been released. It is the v1.9.2 patch. See (Xilinx Answer 31572) for more information and to obtain the patch.
