ModelSim-Altera Simulation of IP Compiler for PCI Express is Slow

Simulation that uses the PCI Express BFM, or simulation of an IP Compiler for PCI Express variation that targets a Stratix IV GX or Arria II GX device, is slow in the ModelSim-Altera simulator.

This issue affects simulation of all IP Compiler for PCI Express variations when the simulator runs the PCI Express BFM, and simulations of variations that target a Stratix IV GX device that do not run the BFM.

This issue has no workaround. You can use a different simulator to simulate your design.

This issue will be fixed in a future version of the IP Compiler for PCI Express.
