Xilinx Blocks

This chapter describes each Xilinx block in detail. Xilinx blocks are grouped within six categories, also shown in the Simulink library browser. They are:

Basic Elements

Communication

DSP

Math

MATLAB I/O

Memory

State Machine

Basic Elements

The Xilinx Basic Elements library includes the standard building blocks for digital designs. Using these blocks, you may insert delay, change the sample rate, and introduce constants, counters, multiplexers, etc. The Basic Elements library also has two special blocks: the System Generator and the Black Box.

System Generator

The System Generator is a special Xilinx block that invokes the tool’s code generation software.

By placing the System Generator token on your Simulink project sheet, you can generate HDL and Xilinx LogiCOREs for all the Xilinx blocks on that sheet and on any sheets beneath it in the hierarchy. The System Generator block parameters dialog box allows you to tailor your

Simulink simulation and code generation.
