Cannot Simulate Auto-Rate Negotiation in CPRI IP Core VHDL Models that Target Cyclone IV GX Devices

Environment

  • Quartus® II Subscription Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT

    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.
