Why does the eCPRI IP assert mac_source_sop and mac_source_valid after the mac_source_ready is de-asserted?

Environment

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

    Due to the ready latency of the eCPRI IP's mac_source_ready is 3 clock cycles, you may observe the mac_source_sop and mac_source_valid are asserted after the mac_source_ready is de-asserted.

    Resolution

    This is an expected behavior of the IP.

    This information has been updated in the eCPRI IP User Guide.
