1 At-speed testing is becoming increasingly difficult with external testers as the speed of microprocessors approaches the GHz range. One solution to this problem is built-in self-...
Excessive switching activity during scan testing can cause average power dissipation and peak power during test to be much higher than during normal operation. This can cause prob...

Transient Signal Analysis is a digital device testing method that is based on the analysis of voltage transients at multiple test points. In this paper, the power supply transient...
1 This paper addresses the problem of testing path delay faults in a microprocessor using instructions. It is observed that a structurally testable path (i.e., a path testable thro...
A novel design-for-test (DFT) technique is presented for designing a core with a “virtual scan chain” which looks (to the system integrator) like it is shorter than the real s...
