Timing Violation Trigger
By default, the software will display all violation triggers in the Timing Violation Trigger
window. You can select subsets of these trigger events from the drop down menu.
The following categories are available (see Figure 2.19 on page 52 ).

DRAM Operations

Read/Write Commands

Low Power States

Initialization Commands
IMPORTANT! To use the JEDEC specified values that match the user defined parameters in Memory
Controller configuration, click the Refresh Timing Violation Symbol Values button
(see figure below) to apply that set of values to all the entries in this section. They can be
modified after this action, if desired.
Below is the list of timing violations the user should set manually in Recording Options as
these cannot be automatically calculated based on DIMM selection parameters:

V13: READ to READ (different rank, same DIMM) < tDRRTR

V14: READ to READ (different DIMM) < tDDRTR

V16: READ to WRITE (different rank, same DIMM) < tDRRTW

V17: READ to WRITE (different DIMM) < tDDRTW

V19: WRITE to READ (different rank, same DIMM) < tDRWTR

V20: WRITE to READ (different DIMM) < tDDWTR

V22: WRITE to WRITE (different rank, same DIMM) < tDRWTW

V23: WRITE to WRITE (different DIMM) < tDDWTW
Note:
The default value is 0, which results in the timing violation NOT being used for triggering or error
analysis.
