The VCD Sink block exports Simulink signals to a third-party waveform viewer.
When you run the simulation of your model, the VCD Sink block generates a value
change dump (.vcd) <VCD Sink block name>.vcd file, which a third-party waveform
viewer can read.
To use the VCD Sink block in your Simulink model, perform the following steps:
1. Add a VCD Sink block to your Simulink model.
2. Connect the simulink signals you want to display in a third-party waveform
3. Run the Simulink simulation.
4. Read the VCD file in the third-party waveform viewer.
If you use the ModelSim software to view waveforms, run the script
<VCD Sink block path>_vcd.tcl where the path is the hierarchical path of the block in
the Simulink model. That is: <model name>_<subsystem names>_<block name> each
separated by underscore character.
This Tcl script converts VCD files to ModelSim waveform format (.wlf), starts the
waveform viewer, and displays the signals. If you use any other third-party viewer,
load the VCD file directly into the viewer.
The VCD Sink block does not have any hardware representation and therefore does
not appear in the VHDL RTL representation created by the
