In this papert a new approach to migrating test pro-grams is presented. A virtual ATE model based on object-oriellted paradigm isdeveloped; it runs Test C++ (an intermediate test control language) programsand TeIF (Test Intermediate Format - an intermediate pattern), migrates testprograms among three kinds of ATE (Ando DIC8032, Schlumberger S15 andGenRad 1732) and gellerates test patterns from two kinds of CAD (Daisy andPanda) automatically.展开更多
