Arria V GT CPRI IP Core Variations at 9.8304 Gbps Might Not Achieve Timing Closure

Environment

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

    Critical Issue

    Description

    If your CPRI IP core variation targets an Arria V GT device and has CPRI line rate set to 9.8304 Gbps, your CPRI IP core may fail to achieve timing closure.

    Resolution

    This issue has no workaround. However, beginning in version 12.0 SP1 of the CPRI MegaCore function, this issue occurs only if your variation includes one or more antenna carrier interfaces.

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