Abstract :
The quality of synthesis schemes and of macro-gate libraries as well as of design-for-testability approaches can also be decided by means of testability measures performed on the final or even intermediate design. Such an approach is significantly improved by outlining a method to include within the fault set the parametric bridging faults internal to macro-gates, that model many defects actually present in CMOS circuits. The presented scheme exploits the separation between local and global fault detection for such faults, extending the testability measures for random testing via the key definition of random detection probability for a bridging fault. Different macro-gate libraries are compared by means of such testability measures performed on well-known benchmark circuits
