Abstract

This paper presents delay test data collected from testchips fabricated in a 0.18驴 technology.The experimentaldata shows that process monitor structures such as on-chipring oscillators are effective in identifying slow partswhile performing transition fault testing at frequenciesslower than the rated frequency.
