This topic explains how to simulate a complete mixed language/mixed flow design that includes AMD HDL blocks, HDL modules, and a Simulink block design.

Model Composer simulates black boxes by:

  • Automatically launching an HDL simulator
  • Generating additional HDL as needed (analogous to an HDL test bench)
  • Compiling HDL
  • Scheduling simulation events
  • Handling the exchange of data between the Simulink and the HDL simulator

This is known as HDL co-simulation.
