Abstract
A system and method are provided for synchronizing data collected from asynchronously clocked circuitry. The method provides an apparatus having inputs to accept a first clock signal and which has a plurality of devices synchronously timed to a third clock, but asynchronous from the first clock signal. Data frames are simultaneously collected for the plurality of devices, at a second clock repetition rate synchronous to the first clock, of device output detection events responsive to the trigger signal. The second clock repetition rate is greater than the first clock repetition rate. High contrast data frames are saved of device output detection events. A determination is made of a first device in the circuit block acting as the third clock trigger. Saved data frames with first device output detection events are recognized as synchronization frames, and the saved data frames are organized around the synchronization frames.
