Warning Messages Reporting Ignored SDC Constraints

Environment

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

    Critical Issue

    Description

    During compilation of a Qsys-generated IP core, the TimeQuest Timing Analyzer may display warning messages indicating that SDC constraints are being ignored. These messages appear because TimeQuest reads the altera_avalon_half_rate_bridge_constraints.sdc file even though the Half Rate Bridge feature is not used.

    This issue affects all Qsys-generated configurations.

    This issue has no design impact.

    Resolution

    To prevent display of the warning messages, remove the altera_avalon_half_rate_bridge_constraints.sdc file from the project and from any .qip file.

    This issue will be fixed in a future version.
