Design & Implementation of Integrated Circuit Tester

Abstract

Nowadays, technology has been consecutively developing. However, silicon technique (semiconductors), which had made great development, specially integrated circuits (ICs). The ICs consist of a large different number of electronic components packaged in small size with many inputs and outputs. This makes their test more difficult and complexity.

This work is about designing and implementation of a simple TTL ICs tester using a personal computer. This tester composed of hardware design matching with the CPU by special software. The hardware is to equip the device under the test (DUT), and format the signaling flow. Since the software provides interfacing technique, testing signals, get the device response, and view the result of testing. In addition the software offers an attractive testing environment easy to deal with.

The result of testing the project showed that it could check TTL IC easily and fast. The test proves the accuracy of the designed tester to evaluate ICs under test according to their datasheets and truth table.
