System and method for data synchronization

A system for synchronizing data collected from a device under test with asynchronously clocked circuitry, the system comprising:

• a pulse generator to supply a first clock signal at a first clock repetition rate, a second clock at a second clock repetition rate greater than the first clock repetition rate, and a synchronous trigger signal, the pulse generator supplying the first clock and trigger signals to a device under test (DUT) having a circuit block including a plurality of devices synchronously timed to a third clock that is asynchronous from the first clock signal;
• a data collection device having an input connected to the pulse generator to receive the second clock signal and an input to simultaneously collect data frames for the plurality of devices at the second clock repetition rate, of device output detection events responsive to the trigger signal;
• a data analysis module having inputs to accept the first and second clock signals, and the collected data frames, the data analysis module saving high contrast data frames of device output detection events, determining a first device in the circuit block acting as the third clock trigger, and recognizing saved data frames with first device output detection events as synchronization frames;
• and,
• an integration module having an inputs to accept the first and second clock signals, the saved data frames, and the synchronization frames, and having an output to supply the saved data frames organized around the synchronization frames.
