TESTING YOUR DESIGN

When you think you've got your design working properly, press the "Run Test" button in the bottom right corner of the Workbench. This will automatically switch to the Test setup and start a waveform generator/recorder pre-programmed with a test sequence.

You will see the input waveforms being fed to the chip and the output waveforms that it is producing. The expected output waveforms are shown in grey for comparison.

When the test is finished, you will be given a summary of the results. If the design passes, you will be allowed to proceed to the next design task.

Note that it doesn't matter if your output waveforms aren't perfectly square or they wiggle up and down a bit, as long as they have the right logic levels at the right times. Also, there is some tolerance allowed in the timing, so your actual outputs can rise and fall a little later than the expected waveforms would indicate without affecting your Correctness score.
