Memory Controller Returns Wrong Data

Environment

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

    Critical Issue

    Description

    For ALTMEMPHY-based designs that use the high-performance controller II (HPC II) architecture with CHIP ROW BANK COL selected for the Local-to-Memory Address Mapping option in SOPC Builder, the memory controller returns incorrect data. When you initialize the memory content with the initialization data file, the fetched memory content does not match the initialization data file. This issue does not affect operation in hardware.

    This issue affects ALTMEMPHY-based designs that use the HPC II architecture with CHIP ROW BANK COL selected for the Local-to-Memory Address Mapping option in SOPC Builder.

    Your design fails to simulate.

    Resolution

    Select CHIP BANK ROW COL for the Local-to-Memory Address Mapping option instead.

    This issue will not be fixed.
