5.5.2. Generating MIPI D-PHY IP Design Example with External Loopback Enabled for Simulation

To generate the design example for simulation with external loopback in the MIPI D-PHY IP, follow these steps:

  1. On the Example Design tab, ensure that the Simulation parameter is set to True.
  2. Choose the required Simulation HDL format, either Verilog or VHDL.
  3. On the Example Design tab under the D-PHY IP tab, ensure that the Sim External Loopback Enable parameter is set to true.
  4. For the TX link, ensure that the Skew calibration enable and Periodic calibration enable parameters under Link n Calibration are set to True.
  5. For the RX link, ensure that the Skew calibration enable parameter under Link n Calibration is set to True.
  6. Ensure that both the RX and TX links have the same bit rate and number of data lanes.
  7. Configure the parameters as appropriate for your needs and click File > Save to save the current settings into the IP variation file (<user instance name>.ip)
