RapidIO Parameter Values Modified in SOPC to Qsys Conversion

Environment

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

    Critical Issue

    Description

    If you open an SOPC Builder system in Qsys to convert it to a Qsys system, every RapidIO MegaCore function instance in the system reverts to the default disabled value for the following parameters:

    • Port Write Tx Enable
    • Port Write Rx Enable
    • I/O read and write order preservation
    • Prevent doorbell messages from passing write transactions
    • Data Messages Source Operation
    • Data Messages Destination Operation

    This issue affects all RapidIO variations in a Qsys system created by converting an SOPC Builder system to Qsys, in which one or more of the preceding parameters is enabled.

    A design based on a Qsys system created by converstion from an SOPC Builder system might not function correctly. It might have incorrect parameter values for these RapidIO MegaCore function parameters.

    Resolution

    To fix the problem in your system, after conversion, edit each RapidIO MegaCore function instance in your Qsys system, and set the parameters to the correct values.

    This issue is fixed in versison 10.1 SP1 of the RapidIO MegaCore function.
