Programming a plurality of states having respective threads is achieved by an event engine and a computer controlled GUI causing the event engine to monitor a signal and execute an action based thereon. The GUI programs an event and several states and causes the event engine to traverse between the states upon reaching the event. The GUI further programs a logic chain which unifies the threads. A method unifies several threads by selecting and executing a logic operation. The method further configures several states and causes traversing between them. The GUI may be deployed co-functionally with debuggers, logic analyzers, scopes, utilities, and software development tools. The results of the GUI are automatically transformed into program code which programs the event engine to operate during debug of a device under test by monitoring for events and taking action based thereon.
