The Real‐Time Statistics Window see Figure 4.2 on page 153 ) displays Link Utilization,
performance measurements, and statistical values for a DDR traffic plotted in real time.
Kibra can monitor up to eight ranks simultaneously, and displays the important
measurements for each time interval (approx. 1/4 second).
The items monitored in RTS are:
 Read
 Write
 Power Down
 Self‐Refresh
 MRS Commands
 RC Commands
 ZQs
 ZQl
 Refresh
The display shows the events occurring in real‐time. For the monitored items, the current
value for a sample interval is shown, along with the maximum value seen during this RTS
session. In addition, the throughput is shown as a percentage of the overall bus
bandwidth. (This is based on either 4 or 8byte bursts. (It is not accurate when OnTheFly
burst mode is in use, since Kibra does not see this on the signals under analysis.)
The Scrolling/Navigation Bar in the RTS view works the same as the Waveform view.
