Design and Implementation of Graphical User Interface for Interface Board Component Testing

Abstract

An interface board, load board, or design under test (D UT) board is a circuit board designed to serve as an interface between the automatic test equipment (ATE) and the DUT. The interface board consists of several electronic components to set up the DUT for testing. It is very crucial that all the electronic components on the interface board operate and function according to the specification to ensure the correct testing operation is performed by the ATE. Therefore, in this study, we develop a graphical user interface (GUI) software to automate the test program generation of testing the resistor components on the interface board via analog pin unit (APU). The GUI has been developed by using Visual Basic programming language. The test engineer can select the resistor to be tested based on its identification. Subsequently, the test program is generated which contains forced current or voltage values to measure the resistance. The generated test program can be passed to the ATE and the test can be performed via APU to identify the malfunction resistor on the interface board. Ultimately, the automation of test program generation increases the efficiency of testing components on the interface board.
