Sometimes it is important to add one or more existing HDL modules to a Vitis Model Composer design. The HDL Black Box block allows VHDL and Verilog to be brought into a design. The Black Box block behaves like other Model Composer HDL blocks - it is wired into the design, participates in simulations, and is compiled into hardware. When Model Composer compiles a Black Box block, it automatically connects the ports of the Black Box to the rest of the design. A Black Box can be configured to support either synchronous clock designs or multiple hardware clock designs based on the context and Model Composer Hub block settings.

Black Box Configuration M-Function	Describes how to create a black box configuration M-function.

HDL Co-Simulation
Configuring the HDL Simulator	Explains how to configure the Vivado® simulator or Questa to co-simulate the HDL in the Black Box block.
Co-Simulating Multiple Black Boxes	Describes how to co-simulate several Black Box blocks in a single HDL simulator session.
