Why do the RX EQ parameter values set in the Analog Parameters tab of the GTS Serial Lite IV FPGA IP GUI not take effect?

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 24.2, the RX EQ parameters you set via the Analog Parameters tab of the GTS Serial Lite IV FPGA IP GUI will not take effect.

Resolution

To work around the above problem, you can set the RX EQ parameters via the following two methods:

1. Apply the QSF assignments:
   • set_instance_assignment -name HSSI_PARAMETER "rx_eq_vga_gain=<parameter_value>" -to <RX_SERIAL_PIN> -entity <TOP_LEVEL_NAME>
   • set_instance_assignment -name HSSI_PARAMETER "rx_eq_hf_boost=<parameter_value>" -to <RX_SERIAL_PIN> -entity <TOP_LEVEL_NAME>
   • set_instance_assignment -name HSSI_PARAMETER "rx_eq_dfe_tap_1=<parameter_value>" -to <RX_SERIAL_PIN> -entity <TOP_LEVEL_NAME>
2. Manually write to the corresponding registers via the Avalon-MM interface.

This problem is fixed beginning with the Quartus® Prime Pro Edition software version 24.3.
