Currently, we are using ZCU111 & ZCU216 with matlabsimulink. Matlab/simulink provides DIP switch, LED, button and so on (see left figure). But we want to use the digital IO (e.g. PMOD0_0) pins. How can we use this without a library for it in matlab/simulink??? Any help / suggestions would be greatly appreciated.

Hi Aera,
To use the digital IO (e.g. PMOD0_0) pins on the ZCU111 and ZCU216 boards without a pre-existing block in the library in Simulink, you can follow the below steps:
  • Develop Custom IP by using HDL Coder or write your custom Verilog/VHDL code to interface with the PMOD pins.
  • Import your custom IP as an HDL block into Simulink using the SoC Blockset.
  • Ensure that your custom HDL code properly maps the physical I/O pins and configure the FPGA pin constraints file (XDC file) to map the I/O signals to the corresponding PMOD pins on the ZCU board.
  • Design a Simulink model that represents the logic you want to deploy to the digital I/O.
  • Use HDL Coder to generate HDL code for the design.
  • Synthesize and implement the generated HDL code in Xilinx Vivado, ensure that PMOD pins are set as the I/O in the constraints file.
