This paper presents a methodology that significantly reduces the cost of test program set development through Iconic Programming Software and in addition simplifies portability between different ATE. The method achieves these goals through a user-friendly interface, which is largely independent of the ATE but can still produce a standardized test specification if required. This method is based on an Aerospatiale Matra Test and Services tool "VISUAL ATE" which requires no particular knowledge of a test programming language. The developer can concentrate on the technology of the equipment to be tested and is not distracted by details of the equipment used to perform the test. The method enables the application of a bottom-up program development methodology that gives the user the opportunity to incrementally develop his test program. This leads to cost-savings through maximum re-use of developments starting from design through to end user maintenance.
