Efficient interconnect test patterns for crosstalk and static faults

Abstract

This paper introduces effective test patterns for system-on-chip and board interconnects. Initially, "6n" patterns are introduced to completely detect and diagnose both static and crosstalk faults, where "n" is the total number of interconnect nets. Then, more economic "4n+1" patterns are described to test the crosstalk faults for the interconnect nets separated within a certain distance.
