Why are there timing violations on the *pld_fpll_shared_direct_async_out_hioint[2] clock domains within the Agilex™ 7 device F-Tile PMA/FEC Direct PHY Multirate FPGA IP?

Environment

  • Intel® Quartus® Prime Pro Edition
  • Interfaces
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem with the Agilex™ 7 device F-Tile PMA/FEC Direct PHY Multirate FPGA IP in the Quartus® Prime Pro Edition Software version 22.4 and earlier, you might see timing violations on the following clock transfers:

    From Clock:
    *_auto_tiles|*__reset_controller_src_divided_osc_clk    

    To Clock:
    *_auto_tiles|*|hdpldadapt_tx_chnl_*|pld_fpll_shared_direct_async_out_hioint[2]

     

    Resolution

    Violations between these clock domains are invalid and can be avoided using a set_false_path command.

    This problem is scheduled to be resolved in a future release of the Quartus® Prime Pro Edition Software.
