发明名称 Fault block detecting system using abnormal current
摘要 In a semiconductor device formed by a plurality of logic blocks, a plurality of functional test patterns are generated and transmitted to the semiconductor device, and it is determined whether an abnormal current flows through the semiconductor device. When an abnormal current is detected, a fault block is determined in accordance with a table for storing the functional test patterns and the logic blocks operated by the functional test patterns.
