Why is the F-Tile CPRI PHY Intel® FPGA IP in the generated design example not resetting properly after FPGA configuration?

Description

Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 22.3, there is a problem in the RTL codes of the F-Tile CPRI PHY Intel® FPGA IP Design Example file cpriphy_ftile_hw.v. The reset status signal ninit_done from the Reset Release Intel® FPGA IP is not connected to the F-Tile CPRI PHY Intel FPGA IP reset ports. Hence, the reset signal does not take effect during the hardware run.

Resolution

You can add the ninit_done and init_done signal to i_reconfig_reset, i_rest_n, i_tx_rst_n and i_rx_rst_n in cpriphy_ftile_hw.v file under the dut_wrapper module.

          .i_reconfig_reset          (i_reconfig_reset | ninit_done),  //active high
          .i_rst_n                   (i_rst_n[cpriphy_inst] & init_done ),
          .i_tx_rst_n                (i_tx_rst_n[cpriphy_inst] & init_done ),
          .i_rx_rst_n                (i_rx_rst_n[cpriphy_inst] & init_done ),

This problem is fixed beginning with the Intel® Quartus® Prime Pro Edition Software version 22.4.
