A system capable of testing common digital integrated circuits used in printed circuit board assemblies will enable laboratory staff to both verify the working operation of the integrated circuits kept in inventory for unit sustainment and service and assist technicians in their efforts to debug these assemblies should they fail acceptance testing. This system should be easily extendable with the use of test scripts that allow specific tests for different integrated circuits. A PC application will interface an electronic test fixture containing the integrated circuit under test to a host PC capable of controlling the test fixture and performing the specified tests. This program should also be capable of generating reports describing the outcome of each test, including descriptions of specific failures. This system would be composed of two distinct parts: 1. A test fixture in which the integrated circuit is inserted for evaluation and contains all necessary electronics to perform testing of these components’ logic tables. The on-board electronics should be capable of generating logic-level voltages to both power the device under test as well for application to the chip’s logic inputs. The test fixture should also be capable of reading the device’s output signals for evaluation of the device’s logic functions. 2. A PC application allowing a user to control the test fixture and run a test script for a given integrated circuit. This application should be capable of controlling the electrical signals generated by the test fixture as well as reading the outputs recorded by the test fixture. This application should also be able to store test results of all integrated circuit diagnostics that detail the specific tests performed as well as any failures observed.
