Using the Pattern Generator

The pattern generator provides programmable digital output that can be used to stimulate and control a system under test. These exercises will show you how to program the pattern generator so that it provides a pattern of "walking ones." Because the pattern generator is an output module, the timing analyzer will be used to view the pattern generator’s output.

These exercises also show you a simple process that represents basic stimulus/response testing. For example, if you are applying the "walking ones" pattern from the pattern generator to a memory, you can use the timing analyzer to see if the "walking ones" pattern is being written to and read from memory properly.

In this chapter, you will:

Connect the pattern generator

Turn on the timing analyzer

Change a label name

Modify channel assignments

Set up the timing analyzer trigger

Add a pattern generator label to the timing waveform display

Set up the pattern generator format menu

Program the pattern generator output

Add program lines

Start the pattern generator and view the walking ones pattern

Stop the pattern generator
