Aurora 8B10B - Slow simulation run time with Artix-7 GTP and Virtex-7 GTH

Description

When Aurora 8B10B is targeting Artix-7 GTP and Virtex-7 GTH, the simulation is slower.

This answer record explains why this occurs.

Solution

With 7 series GTP and GTH, Aurora 8B10B implements the Rx reset sequence provided in (Xilinx Answer 53561) and (Xilinx Answer 53779).  

This reset sequence requires the SIM_RESET_SPEEDUP attribute of the GT simulation model to be set to FALSE for proper functionality in simulation. 

This emulates hardware reset behavior in detail and causes the simulation to be run for longer.
