As avionics software complexity increases, traditional techniques for avionics software validation and testing become time consuming, expensive, and ultimately unworkable. New test issues arise with the development and maintenance of complex 'super federated' systems like that of the B-2 and highly integrated systems like that of the F-22. Upgrades to existing weapon systems that produce a blend of federated and integrated architectures further complicate the problem. This paper discusses the limitations of current approaches, equipment, and software. It defines a next generation of avionics software validation and test procedures, along with the hardware and software components that are required to make the process work. The central goals of the process and components are to reduce development and maintenance costs, to minimize womanpower requirements, to decrease the time required to perform the testing, and to insure the quality of the final product. The process is composed of unit test, component test, configuration item test, subsystem test, integration test, avionics-system test, and weapon-system test. Some of the topics covered are as follows: automated testing of avionics software, real-time monitoring of avionics equipment, nonreal-time and real-time avionics emulation, and real-time simulation. This paper is based upon several years of experience in the following areas: (1) research and development of new technologies to improve the supportability of weapon-system software; and (2) design and implementation of facilities for the development, enhancement, and test of avionics software.
