Abstract

In this paper we analyze the coverage of distributed delaydefects, on untested but functionally sensitizable paths,achieved by robustly testing a subset of paths in the circuit.This is measured by translating the information gained fromrobust testing into a set of linear constraints on edge delaysand then using these to bound the circuit delay. Surprisingly,the results of our experiments on ISCAS benchmarkcircuits show that robust testing of a subset of paths in thecircuit, may not cover distributed delay defects on the remainingpaths very well at all.
