ABSTRACT:
A circuit and related method for distributing events in an event stream (i.e., an electronic signal having a plurality of rising edge transitions and falling edge transitions). The circuit distributes the events in a primary event stream across multiple secondary event streams in such a way that the event rate in each of the secondary event streams is lower than the event rate in the primary event stream, but the relative timing of the events in the primary event stream is maintained in each of the secondary event streams. The secondary event streams can then be provided to respective timestamp circuits, which record the times at which events occur in the secondary event streams. Since the relative timing of the events in the primary event stream is maintained in each of the secondary event streams, the multiple timestamp circuits collectively record the times at which events occur in the primary event stream. The circuit and related method can be used when debugging/testing semiconductor devices.
