Sometimes it is important to add one or more existing HDL modules to a 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 System Generator token settings.
