5.2 Logic Development using MATLAB Simulink

MATLab Simulink provides a powerful method of developing logic using a high level design tool

that integrates hardware into the MATLAB Simulink environment. Complex signal processing

designs can be developed rapidly using the Simulink block diagrams interacting with the actual

hardware in real time. Gateways between MATLAB Simulink and the hardware allow data to flow

between the actual hardware and MATLAB, bringing the power of MATLAB to the logic

development process.

Simulink blocks diagrams are directly translated into logic using the Xilinx System Generator tool.

For each supported product, a hardware interface layer of Simulink components is provided that

allows the hardware to be used in the the Simulink design.. Simulink components from the

various libraries provided by Mathworks, Xilinx and Innovative interface with this hardware

interface layer for building the application logic on the product. The Xilinx place and route tools

are used for the logic build as in any HDL project.

Here is a typical Simulink block diagram design. Notice the Xilinx icon in the upper left; this is the

Xilinx System Generator control block. This block provides the link to the Xilinx place and route

tools used to implement the logic. The other blocks are mixture of hardware interface

components, such as the Quixote A/D converters, SRAM and DACs. The remaining blocks are

Simulink functions for control, display and data formating.

MATLAB Simulink library components are shown in the library for each product. Examples

illustrating the use of MATLAB are provided in each product section.
