A FLEXIBLE APPROACH TO TEST PROGRAM CROSS COMPILERS

Abstract

The initial development costs of test programs and test hardvvare range from $5,000 to $30,000 or more. As device speeds or production needs increase, the need to test an existing device on a different tester often arises. A solution to minimize this development cost is to recycle the exixting test program, patterns and the device interface boards. This paper describes how the UNIX tools, LEX and YACC, were applied to solve this problem. In this case, Ando DIC 8035 test programs, paeterns and bad boards were used on a Credence Vista Series LT-1101 test system. The program ando2lt (Ando to LT) is the first of the test program crosscompilers using these tools. The flexibility of this approach led to the reuse of over 44% of the ando2lt code in the second cross-compiler sts2It.
