Logic State Analyzers-A New Instrument for Analyzing Sequential Digital Processes

Logic state analyzers are used to monitor, or measure, the sequence of program and data flow in sequential processors, such as computers and microprocessors, as a means of debugging, testing, and troubleshooting these processors. The application of these measurements is discussed using examples of debugging and troubleshooting techniques made possible by logic state analyzers. The capabilities required to implement these measurements are set forth using the previously described measurements. These measurement capabilities, then, become the functional definition of a logic state analyzer. Finally, the block diagram required to implement these measurement capabilities is developed as a further means of describing the measurement of logic or data sequences and the application of these measurements to troubleshooting, debugging, and testing sequential digital machines and systems.
