Black Box Examples
signal is represented in two ways in the ModelSim viewer – binary and analog. The
ModelSim waveforms for the black_box_ex5 simulation are shown below.
3. Double click on the Simulink scope in the model. The output is shown below and
resembles the analog signal in the ModelSim waveform viewer.
The black box in this example is configured using mask parameters. There are many
situations in which this is useful. In this case, the number of black box input ports, i.e.,
the number of scope inputs, is determined by a mask parameter.
