Component Description
Testbench Control This block controls the test sequence of the simulation and generates the necessary stimulus signals to the TX and video pattern generator blocks.
TX checker This checker verifies if the TX serial data contains a valid TRS signal.
RX checker

This checker detects the trs_locked signal from the RX protocol and compares the actual number of transceiver reconfigurations performed versus the expected number.

Parallel-in serial-out regsiter

Available when you select Without PHY in Select Simulation Type

This block acts as the TX transceiver, converting parallel TX data to serial data.

Serial-in parallel-out regsiter

Available when you select Without PHY in Select Simulation Type

This block acts as the RX transceiver, converting serial RX data to parallel data.
