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.
