2.3.2.1.1.1 Pattern Match
The level trigger is a pattern match detector. You can configure it to match any combination of 0,1
or don't cares across all 18 (or 36) channels. The Pattern Match Editor is displayed below
ADD a Signal - Highlight a defined signal from the left portion of the window and click the "+" button to
add it to the Pattern Match. You can also just "Double-Click" the defined signal to automatically add it.
NOTE: High Level signal definitions (such as State, I2C, or etc) cannot be added directly as a
complete signal. However, the individual portions of the signal (such as Enable above) can be added in
the same manner. To see the sub-portions of a signal, click the "expand" button in the left column next
to the signal's name, then add the sub portions in the same manner as any other signal.
For instance, if you have defined a State signal like the one above (Address) and you only want to
add the Enable signal to the pattern match, then expand it and double-click on Enable.
Note: If a signal is valid for the trigger configuration, a green icon will be displayed next to it.
Any other icon, such as the blue circle above on the Frame Sync channel of the Address
signal, indicates a channel state that is invalid for triggering. This particular icon indicates that
the channel has been configured as 'Ignored' in the signal definition editor.
Delete a Signal - Highlight a signal in the right portion of the window (or mouse-over its bit
selections) and click the "-" button to delete it from the Pattern Match.
