Abstract

An ATPG for resistive bridging faults in combinational or full-scan circuits is proposed. It combines the advantages of section-based generation and interval-based simulation. In contrast to the solutions introduced so far, it can handle static effects of arbitrary non-feedback bridges between two nodes, including ones detectable at higher bridge resistance and undetectable at lower resistance, and faults requiring more than one vector for detection. The developed tool is applied to ISCAS circuits, and a higher efficiency compared with other resistive bridging fault as well as stuck-at ATPG is reported. Information required for accurate resistive bridging fault simulation is obtained as a by-product.
