Internal Error: Sub-system: FSV, File: /quartus/fitter/fsv/fsv_module_lvds_cv.cpp, Line: 2420

Environment

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

    Due to a problem in the Quartus® II software version 12.0, you may see this internal error if your design implements an ALTLVDS_TX megafunction with the tx_outclock signal driving core logic. This internal error occurs for designs targeting Arria® V or Cyclone® V devices.

    Resolution

    Using the tx_outclock signal to drive core logic is unsupported.

    The Quartus II software begining with version 12.1 reports an error message describing the problem instead of producing an internal error.
