Bank State View Teledyne LeCroy
3.5 Bank State View
The Bank State View provides 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. While the waveform gives a chronological view of
commands across the bus, the Bank State View allows the user to view and understand
how the controller is accessing the ranks and banks to improve performance. The user
can collapse/expand multiple signals into individual banks in a rank, show/hide ranks and
banks, and zoom and scroll through the traffic on a specific bank.
Click on the Bank State View icon to display the Bank State View. The navigation in
the Bank State view is similar to the navigation in the Waveform view.
