Why do reads from the reconfig_pdp interface of my F-Tile PMA/FEC Direct PHY Intel® FPGA IP or F-Tile PMA/FEC Direct PHY Multirate Intel® FPGA IP return 0x00000000?

Description

Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 23.2 and earlier, reading from the datapath Avalon® memory-mapped Interface (reconfig_pdp) may return 0x00000000 when the "readdatavalid" port is enabled on the datapath Avalon memory-mapped interface of your F-Tile PMA/FEC Direct PHY Intel FPGA IP or F-Tile PMA/FEC Direct PHY Multirate Intel FPGA IP design.

 

Resolution

This problem is fixed beginning with the Intel® Quartus® Prime Pro Edition Software version 23.3.
