Lattice ispTRACY Usage Guide
Figure 14-9. ispLA Project Setup Window - Trigger Setup options
The options available in the Trigger setup window are based on selected ispTRACY core options. In the Trace
Mode box, One Shot mode will always be available, but Sample After Trigger availability is dependent on selecting
Sample_After_Trigger Mode Logic => ON. The position slider can be used to select the trigger point anywhere
within the data memory depth. There are three preconfigured trigger positions in the drop-down menu box. They
are Pre-Trigger (5% before and 95% after trigger), Center (50% before and 50% after trigger) and Post Trigger
(95% before and 5% after trigger). In the Compare Mode box the options are also dependant on core configuration.
EV0 and EV1 are always available. The comparisons available and number of samples will be determined by the
Size Comparison Logic and Event Counter Size. The equal to comparison is always available. Additions compari-
sons include >, <. !=, <=, >=. The Trigger Condition box configures which event or combination of events will cause
the ispLA program to trigger and upload captured data from the device. In a simple case, this would be set to Wait
for EV0. More complex cases could possible be wait for EV0 and EV1, or after EV1 wait until EV0. The final two
boxed on this screen control the signal polarity of Trigger In (if available) and Trigger Out.
