SignalTap advanced triggering?

Anyone got an example of how to setup advanced or sequential trigger-flow in SignalTap?

I want to trigger a capture on the first '0' after say, 5 succesive '1's on my input, using a 10 x faster-than-my-data capture-clock.

Or can I specify a serial pattern ("111110xxxx" and then trigger) to achieve the same?

Mostly curious about what you can do - rather than desparate for a solution.

Thanks.

    The advanced trigger flow can become very complicated real fast when trying to do complex triggers. I would suggest instead to create a "state based" trigger flow instead of sequential. Then you are able to write a state machine, using counters and events.
