Design of a mini-computer controlled digital integrated circuit tester

The purpose of the thesis is to design, construct, program, and test an automatic integrated circuit test system. The class of integrated circuits tested was restricted to digital integrated circuits. The general concept of testing a digital integrated circuit is based on the truth table of that circuit. The tester consists of a matrix switch, power supplies, a clock, logic circuitry, analog-to-digital and digital-to-analog converters, and a PDP-8/L mini-computer with an automatic send-receive teletypewriter. With the exception of the minicomputer with its teletypewriter and power supplies, the tester was designed, constructed, programmed, and tested. Computer programs for testing some digital integrated circuits and their results of testing are shown.
