Alert Trigger (DDR4)
This special trigger allows triggering Kibra Hardware on the specific length of an "Alert"
signal in DDR 4. This signal is used for the occurrence of an Alert for CRC or C/A Parity
error. Their parameters may be adjusted in the Memory Controller section as follows:
 Change "C/A Parity Latency Mode" setting to enable and adjust "Parity Alert"
pulse
 Change "CRC" setting to enable/Disable "CRC Alert" option.

2.6.3 Recording Options - Advanced Triggers Tab
In the Recording Options Dialog you can set the user defined Trigger and Filter options in
the Advanced Triggers tab. This tab displays three areas, the Command Read/Write
Trigger settings and the Sequence Trigger settings (see
Figure 2.27 on page 60 ). The three
options on this tab are explained below.
Selection of the signals for triggering works similar to how they are displayed in the GUI.
(High and Low). The active low or active high nature is already taken into account in the
signal naming. For example, CS0 being selected means the electrical value goes low, but
CS0# is thus shown as high.
Triggering can be performed on a specific command, on a Read, Write or both.The Read
and Write commands can be triggered on a specific physical address or users can define a
sequence of commands or signal states to trigger on. For example, Write to
Addr=0xDEED.
Each of these triggers are “OR” conditioned with any other trigger selection including the
JEDEC Violations selected on the Basic Settings tab. See
“Timing Violation Trigger” on
page 52 . Triggering can also be performed on JEDEC command timing violations.
Any Trigger detected from these settings, including the Timing Violation triggers will
automatically trigger a pulse on the External OUT SMA on the rear of the Kibra 380 or
Kibra 480 hardware. See
“External Trigger Out” on page 19 .)
Kibra provides triggering on RC commands. To activate you user should select the correct
memory type RDIMM/LRDIMM/SORDIMM, and then the RCD commands trigger is
available in the Advanced Triggers Tab.
