Due to a bug in the Windows version of the Intel® Quartus® Prime software version 19.4 and earlier, the transceiver E-Tile Native PHY IP Embedded Streamer may hang when performing transceiver dynamic reconfiguration on Intel Stratix® 10 TX, DX, and MX devices. The Linux version of the Intel Quartus Prime software is unaffected.
The Intel Stratix 10 E-Tile Native PHY IPs generated using the Windows version of the Intel Quartus Prime software version 19.4 and earlier may have an incorrect last word of the transceiver configuration file.
To work around this problem you can generate your Intel Stratix 10 device E-Tile Native PHY IP using the Linux version of the Intel Quartus Prime software.
Alternatively you can edit the final word of the transceiver configuration file in the following location.
..\<phy_name>\altera_xcvr_native_s10_htile_<quartus_version>\synth\ alt_xcvr_native_rcfg_strm_params_<random_string>.sv file
For example:
..\LH_PHYDxUSR0_x1\altera_xcvr_native_s10_htile_1921\synth\alt_xcvr_native_rcfg_strm_params_df5ou5a.sv
Edit the file so that the most significant non-zero nibble is “7” hex.
For example:
Change the final word from 27'h000FFFFFF to 27'h007FFFFFF
Or change the final word from 35'h0FFFFFFFF to 35'h7FFFFFFFF
This problem is fixed in the Intel Quartus Prime software version 20.2.
