SIFA - Bottom Up Evaluation Step 4 << Tutorials Index << Home

Create an instance of the imported VHDL, and add the source and sink ports. The type of the instance is the 'sensible' name that was chosen in Step 1. This instance is probably best placed in the top-level "Architecture" view.

To do this, right-click on the top-level Architecture view (this should be the last item in the hierarchy) and Show. Then, using the graph editing operations (see the user guide), add an instance with ports defining the interface to the imported system.

To correspond with the example in the user guide, instance1::p1 here is defined as a source, and instance2::p3 as a sink. I've chosen the name "ex" for the instance (this is arbitrary though).
