Listing View shows the same data in a list format in columns. The listing view
shows the decoding of each of the buses on a sample by sample basis.
Bank State View displays a Bank by Bank view of the changing bus states. It is
separated by bank to enable a more insightful picture of the activity in a way
that is often obfuscated in a waveform view.
Traffic Summary View gives a tabulation of commands by Rank, bank; perfor‐
mance statistics, and timing and protocol violations. Results Hyperlink back to
points of occurrence within the Waveform, Listing and Bank State views.
