Abstract

The use of functional vectors has been an industry standard for speed binning purposes of high performance ICs. This practice can be prohibitively expensive as the ICs become faster and more complex. In comparison, structural patterns can target performance related faults in a more systematic manner. To make structural testing an effective alternative to functional testing for speed binning, structural patterns need to correlate with functional test frequencies closely. In this paper, we investigate the correlation between functional test frequency and that of various types of structural patterns onMPC7455, aMotorola processor executing to the PowerPC 1 instruction set architecture.
