Critical Issue
Description
If you generate a VHDL simulation model for your CPRI MegaCore function that targets a Cyclone IV GX device, you cannot use it to simulate auto-rate negotiation.
This issue affects all CPRI MegaCore function VHDL simulation models with auto-rate negotiation enabled that target a Cyclone IV GX device
This issue affects simulation only.
Resolution
This issue has no workaround. To simulate auto-rate negotiation, generate and simulate a Verilog HDL simulation model.
This issue is fixed in version 12.0 of the CPRI MegaCore function.
