CoE1502: Using Logic Analyzer

In order to test a real hardware design one need to be able to measure the actual values of bus and signal lines. Logic analyzer is a great aid for this purpose. With it one can collect output signals and view wave forms.

In our class we are using HP 1600 series logic analyzer.

Our design will be synthesized and uploaded to the FPGA device on the "Wild-One" board. The board is connected to the logic analyzer. Thus we can run tests on our design and observe the results with the logic analyzer.

How to use the Logic Analyzer (LA):

The LA has several sets of buttons on its front pannel: The LA also has a 3" disk drive where one can save current setup or waweforms.

When you want to make measurements with the LA, you have to go through the following steps:

  1. Map to target (CONFIG. key)
  2. Set up analyzers (FORMAT key)
  3. Set up trigger (TRIGGER key)
  4. Run measurement (RUN key)
  5. View data (LIST / WAVEFORM keys)

Map to Target (CONFIG. key)

This step configures the LA. Normally you do not need to make any changes here and can skip to the next step.

Set Up Analyzers (FORMAT key)

Set Up Trigger (TRIGGER key)

Run Measurement (RUN key)

View Data (LIST / WAVEFORM keys)

Here we can view the results of our test run and see if we get what we expected. After this step you can go back to trigger setup, or make changes in your design, synthesize, upload and run the measurement again.

Good Luck!
