Abstract For two-pattern at-speed scan testing, the excessive power supply noise at the launch cycle may cause the circuit under test to malfunction, leading to yield loss. This paper proposes a new weight assignment scheme for logic switching activity; it enhances the IR-drop assessment capability of the existing weighted switching activity (WSA) model. By including the power grid network structure information, the proposed weight assignment better reflects the regional IR-drop impact of each switching event. For ATPG, such comprehensive information is crucial in determining whether a switching event burdens the IR-drop effect. Simulation results show that, compared with previous weight assignment schemes, the estimated regional IR-drop profiles better correlate with those generated by commercial tools.
