Precharge - Power-Down
All the banks of a rank go to power‐down idle after receiving a PDE command on that
rank.
Active Power-Down
This state happens when the bank is active, but the rank goes into power‐down state.
Unknown
This state only happens at the beginning of a trace, where insufficient context of prior
states makes the current state undetermined. The application needs to find a valid
command before showing the valid state for that bank.
Legend Display
The DDR Protocol Suite provides a legend that shows the supported states. You can
display the legend for the Bank State view by right‐clicking in the view and selecting Show
Legend. Figure 3.37 shows how to activate the legend and Figure 3.38 shows a snapshot
of the legend. Selecting/deselecting this option toggles between showing and hiding the
legend.
