Configuration Via Protocol (CvP) Not Working for Stratix V Hard IP for PCI Express x2 Variants

Environment

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

    Critical Issue

    Description

    Stratix V GX Hard IP for PCI Express variants using CvP and x2 configuration fail during link training initialization.

    Resolution

    The workaround is to specify a x4 configuration and let the link downtrain to x2. CvP updates work reliably using this workaround starting with release 12.0 of the Quartus II software. This issue will be fixed in a future version of the Quartus II software.
