US Patent 10445219 Extracting transaction level information from a circuit interface

Extracting transaction level information from an interface can include tracking transactions of an interface within an integrated circuit (IC) using a plurality of counters within the IC, wherein the counters generate counter data corresponding to the transactions. The method can include capturing signals of the interface as trace data for a trace window using an integrated logic analyzer within the IC, wherein a start of the trace window begins after a start of the tracking of the transactions using the plurality of counters. The method can also include using a host data processing system coupled to the IC, determining transaction level information for the interface using the counter data and the trace data for the trace window.
