The main object of this Professional Project was to establish a microcomputer based system which could detect faults in digital circuits. Hardware and software for the Motorola 6800 microcomputer system was fully developed. Node level diagnostic programs were then used to pump known "Bit Patterns" into digital circuits and responses recorded via Pseudorandom binary sequence generator using CRC code. This method also known as "Signature Analysis" was then applied to detect faults successfully in Universal Asynchronous Receiver Transmitter or UART Circuits.
