Why does failure happen when running a hardware test with Serial Lite IV design example on the F-Tile of Intel Agilex® Device?

Description

Due to a problem in Intel® Quartus® Prime Pro Edition Software version 22.4 and earlier, HSSI_PARAMETER assignments are missing in the .qsf file of Serial Lite IV hardware example design on F-Tile of Intel Agilex® devices. As a result, hardware tests may fail in external loopback mode.

 

Resolution

To work around this problem in Intel® Quartus® Prime Pro Edition Software version 22.4 and earlier, the user needs to add HSSI_PARAMETER assignments in the .qsf file manually to set values below:

txeq_main_tap, txeq_pre_tap_1,  txeq_pre_tap_2, txeq_post_tap_1, rx_ac_couple_enable, rx_onchip_termination

Please refer to F-tile Architecture and PMA and FEC Direct PHY IP User Guide for assignment values and examples.

This problem has been resolved in the Intel® Quartus® Prime Pro Edition Software version 23.1.
