GTS Transceiver Toolkit Helper Script - The GTS Transceiver Toolkit helper script is a Tcl script that you can use to perform testability features for a GTS PMA such as enabling or disabling different loopback, select a PRBS pattern, set transmitter PMA equalizer parameters, and measure BER. This script is linked in the GTS Transceiver PHY User Guide: Agilex™ 5 FPGAs and SoCs and GTS Transceiver PHY User Guide: Agilex™ 3 FPGAs and SoCs.
