The Automatic Dynamic Response Analyzer (ADRA) is a laboratory tool for developing improved methods of characterizing and measuring the dynamic performance of integrated circuit logic packages. ADRA consists of ensembles of computer controlled electronic equipment which provide a suitable electrical environment for the logic unit under examination, subject the unit to appropriate patterns of shaped pulses, measure and digitize the input/output waveforms, and process the resulting data. This paper describes the ADRA system, its organization and hardware characteristics, and an example of its use.
