Timing Violation Reanalysis
Define Report Boundary
The report result can be limited to a special range of the trace using this section. Like
other range selection sections in DDR Protocol Suite, the user can specify the range by
entering exact timestamps or by selecting from markers/cursors which are already
located in the trace.
Cyclic Row Usage Report
As mentioned above, the cyclic report works in periodic intervals which can be defined
according to time range or the cycle can be reset by a specific command. Cyclic report
shows counters according to each selected row. The main report columns are:
Min Per Cycle: This column specifies the minimum counted count of the target command
in all cycles.
Max Per Cycle: This column specifies the maximum counted count of the target command
in all cycles.
Avg Per Cycle: This column specifies the average counted count of the target command in
all cycles.
Exceed count: This column specifies the number of cycles that the counted count has
exceeded the max allowed count.

The Add Cursor button applies to the selected item. A Cursor pair will be added into the
Waveform view to show where this selected item starts and stops.

Timing Violation Reanalysis
The Timing Violation Reanalysis dialog (see Figure 3.67 on page 148)allows users to
change the timing violation parameters and reanalyze the trace according to new
parameters. This dialog shows the parameters of recording time as the default, and the
user can change the parameters as desired. The trace is the analyzed according to the
new parameters and the violations will be showed in waveform. These new parameters
display when the trace is next opened, but the user can roll‐back the parameters to the
original recording parameters by clicking Load Original Capture Settings. Refer to
"Recording Options ‐ Basic Settings Tab" on page 42 for more information. Click Save TO
Current Recording Options to save the new parameters to the current recording options.
Timing violation re‐analysis also provides the capability to change the CAL value. The CAL
value affects the decoding of commands in addition to changing timings. You can select
