Reliability qualification vehicle for application specific integrated circuits

U.S. Patent Number: 5299204

Abstract: Reliability qualification vehicles are described with internally generated clock and control signals which may be selected in place of externally generated signals for exercising the vehicle. If implemented in gate-arrays, the vehicle may be contained in different sized packages to test the effects of different size packaging on the vehicle. Substantially all the gates of the vehicle are testable. The vehicle may be operated synchronously and its design enables quick feedback and analysis of faulty portions of a cell library or place and route scheme.
