ABSTRACT:
Some embodiments provide a device under test comprising a processing core to support execution debug signals, a debug ring to receive and to transmit the execution debug signals from and to the device under test, a first debug port to receive and transmit the execution debug signals from and to the debug ring, and a second debug port to receive data from observation signal lines of the device under test. The first debug port may transmit execution debug signals to define an event to detect within the device under test, to receive execution debug signals indicating occurrence of the event, and to use a handler to place the device under test in a quiescent state and to instruct the device under test to transmit data of one or more registers. The second debug port may receive the data of the one or more registers from observation signal lines of the device under test.
