Design Topology
Allows you to choose the topology of example design to be generated. The allowable options are Pass-Through and RX Only.
  • Pass-Through showcases the HDMI system built with one HDMI TX Subsystem and one HDMI RX Subsystem, sharing the same Video PHY Controller /HDMI GT Subsystem.
  • RX-Only showcases the HDMI system built with only one HDMI RX Subsystem and Video PHY Controller /HDMI GT Subsystem. A Frame CRC helper core is added to the RX-Only topology to facilitate system monitor and debugging.
Axilite Frequency
Allows you to choose the AXI4-Lite CPU clock. In this release, the following options have been verified.
  • 7 series: 50 MHz, 100 MHz, 150 MHz
  • UltraScale/UltraScale+ Devices: 50 MHz, 100 MHz, 150 MHz, 200 MHz
  • Versal ACAPs: 100 MHz
Video Phy Controller Setting
Allows the configuration of the Transmitter PLL type and Receiver PLL Type to the Video PHY Controller /HDMI GT Subsystem prior generating the example design. It also allows user to selectively opt-out the NI-DRU to optimize resource use if the video resolution they plan to support does not require NI-DRU. See the Video PHY Controller LogiCORE IP Product Guide (PG230) or the HDMI GT Controller LogiCORE IP Product Guide (PG334) for details about NI-DRU requirements for Versal ACAPs.
Example Design Overview
A system block diagram to show the overview of the example design to be generated.
Important: When the example design targets the VCU118 board and Design Topology is set to Pass-Through, the Include NIDRU option under the Video PHY Controller setting is grayed out and unchecked by default.
Note: When the AXI4-Lite clock is set at a higher frequency, it is more likely to have timing violations. You must adjust the clock rate to achieve timing closure without impacting system performance.
