Critical Issue
Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 21.2, the Simplex Avalon Memory-Mapped Interface merging of Local User Avalon Memory-Mapped Interface does not work in F-Tile IPs.
This affects the F-Tile PMA/FEC Direct PHY Intel FPGA IP and should also affect any other F-Tile IPs supporting simplex mode.
Users who are trying to use two simplex IPs in the same hardware location should only enable Avalon Memory-Mapped Interface on one side, not the other. They can use that single enabled port to control Avalon Memory-Mapped Interface for both TX and RX.
