ASI Does Not Support VHDL Functional Simulation Model for Cyclone IV GX

Environment

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

    Critical Issue

    Description

    Serial loopback designs that target Cyclone IV GX devices using the VHDL functional simulation model fail to simulate.

    This issue only affects designs that target Cyclone IV GX devices using the VHDL functional simulation model. The design fails to simulate using the VHDL functional simulation model.

    Resolution

    Use the Verilog HDL functional simulation model instead.

    This issue will be fixed in a future version of the ASI MegaCore function.
