trigger from power off state

Hi, I know there's power up trigger feature in signaltap II, but can it be done in the off -> on transition? Meaning, the board is off, signaltap is waiting for trigger, then I power up the boar...

Yes, I've used this feature before (to capture PCIe power-up waveforms).

Its called a power-up trigger ...

It cannot be used to capture just any power-up signal, eg., the FPGA first has to be configured, and then the SignalTap II logic will wait for the trigger condition. Think of this as a "power-up trigger enable" feature, rather than a "capture power-on waveforms" feature.

Cheers,
