Hi Gibbs,
First configure a digital line to give a trigger out when it receives the NOTIFY stimulus.
From the trigger blocks, you can add an entry to use the Notify event to cause the digital IO trigger.
--setup digital output to strobe when NOTIFY2 event occurs
digio.line[1].mode = digio.MODE_TRIGGER_OUT
trigger.digout[1].pulsewidth = 10e-6
trigger.digout[1].stimulus = trigger.EVENT_NOTIFY2
trigger.model.setblock(blockNumber, trigger.BLOCK_NOTIFY, trigger.EVENT_NOTIFY2) -- strobe the digital output
