Design for test in automotive electronics

Abstract

To ensure proper implementation, the DFT process has to be supported by a comprehensive set of tools for system specification, design verification, testability analysis, test generation and software validation. Any DFT/DFD strategy has to be based on a thorough understanding of the cost of test structure over the life of the automotive products. Without a viable cost of test model it will be impossible to justify the test features added to the module that usually impact the cost of design and are of benefit only for the later stages ofthe product life
