The software provides a list of available commands in the Command drop‐down
list (see red arrow in figure below) for easy selection of signal values. However,
just selecting command value is not sufficient for defining a condition, you
should define other signals values as well.
Defining “Arm” and “Reset” conditions are optional.
“Reset” and “Trigger” conditions can be defined as “Timer” condition instead of
“Signal Transition”. This is useful for defining user defined timing violations.

Note:
Signals displayed in XXXX format represent traditional binary bit positions. So, ODT0 "High"
would be XXX1, and ODT2 "Low" would be X0XX, etc.
Clock Present
Clock Present triggers when either the clock is seen or the clock is disabled for a short
period of time (see
). This can be used to trigger on the clock going
away for a period of time. This is done by using a sequence trigger as follows:
Arm on Clock Present: Clock Disable. This will arm whenever the clock stops for a
short time.
