3.2. Simulation Design Example

The simulation design example contains the major blocks shown in the following figure.
  • An instance of the synthesis design example. As described in the previous section, the synthesis design example contains a traffic generator and an instance of the memory interface.
  • A memory model, which acts as a generic model that adheres to the memory protocol specifications. Frequently, memory vendors provide simulation models for their specific memory components that you can download from their websites.
