Embedded Target for Motorola MPC555

The Demo Model

We have provided a demo model for your use. The Fault-Tolerant Fuel Control System model, shown in Figure 2-1, consists of a plant model with a controller subsystem, the fuel rate controller subsystem.

Figure 2-1: Fault-Tolerant Fuel Control System Model

In the following sections, you will use the demo model and the PIL target to generate the following:

• PIL code to run on the target board. The PIL target automatically invokes the appropriate cross-development tools to compile, link, and (optionally) download and run a target executable.
• A library containing
• The original fuel rate controller subsystem block for use in simulation.
• An S-function wrapper block, generated by the Real-Time Workshop Embedded Coder, that implements the fuel rate controller subsystem for use in software-in-the-loop (SIL) simulation.
• A subsystem block that implements the fuel rate controller subsystem on the host side during cosimulation. This subsystem communicates with generated PIL code running on the target board.
• A master Configurable Subsystem block that represents the above three components. You will plug this block into a plant model and select each of the three components in turn for use in a simulation.

This figure shows a library generated by the PIL target.

Once you start the build process, there is almost no manual intervention required to build all these components.

After building the components, you will use them in normal simulation, SIL simulation, and PIL cosimulation. You will monitor the results of each simulation via the Scope blocks in the model.
