The next step is to create the model instances of required primitives and modules of the system by dragging them from the Tree View into the system. The empty system MyAdderSystem should be open in the Model Editor window and appear as a grey square.
Continue as follows:
The next step is to add sources to your system. Sources are models that do not have input ports, but one or more output ports at which they generate signals or events. Proceed as follows:
It is not possible to run a simulation unless the output of the system is processed by a sink primitive. The Sinks library contains a collection of primitives that do exactly that. There are a number of ways to deal with output data resulting from a simulation. The data can be:
Expand the tree to MLD Libraries→SDF Domain→Sinks. Search for a primitive called Xgraph and drag and drop it into the system Model Editor Window. You now have all the elements needed for the system. The next phase is to connect the model instances.
