2.13. Simulation Testbench

The simulation testbench simulates the HDMI TX serial loopback to the RX core.
Note: This simulation testbench is not supported for designs with the Include I2C parameter enabled.
Figure 19.  HDMI Intel® FPGA IP Simulation Testbench Block Diagram
Table 24.  Testbench Components
Component Description
Video TPG The video test pattern generator (TPG) provides the video stimulus.
Audio Sample Gen The audio sample generator provides audio sample stimulus. The generator generates an incrementing test data pattern to be transmitted through the audio channel.
Aux Sample Gen The aux sample generator provides the auxiliary sample stimulus. The generator generates a fixed data to be transmitted from the transmitter.
CRC Check This checker verifies if the TX transceiver recovered clock frequency matches the desired data rate.
Audio Data Check The audio data check compares whether the incrementing test data pattern is received and decoded correctly.
Aux Data Check The aux data check compares whether the expected aux data is received and decoded correctly on the receiver side.

The HDMI simulation testbench does the following verification tests:

HDMI Feature Verification
Video data
  • The testbench implements CRC checking on the input and output video.
  • It checks the CRC value of the transmitted data against the CRC calculated in the received video data.
  • The testbench then performs the checking after detecting 4 stable V-SYNC signals from the receiver.
Auxiliary data
  • The aux sample generator generates a fixed data to be transmitted from the transmitter.
  • On the receiver side, the generator compares whether the expected auxiliary data is received and decoded correctly.
Audio data
  • The audio sample generator generates an incrementing test data pattern to be transmitted through the audio channel.
  • On the receiver side, the audio data checker checks and compares whether the incrementing test data pattern is received and decoded correctly.

A successful simulation ends with the following message:

# SYMBOLS_PER_CLOCK 	= 2
# VIC               	= 4
# FRL_RATE          	= 0
# BPP               	= 0
# AUDIO_FREQUENCY (kHz)  = 48
# AUDIO_CHANNEL     	= 8
# Simulation pass
