SEMICONDUCTOR INTEGRATED DEVICE, METHOD FOR DETECTING VOLTAGE DROP OF INTEGRATED CIRCUIT, AND METHOD FOR CORRECTING VOLTAGE DROP

摘要

PROBLEM TO BE SOLVED: To detect and appropriately correct drop of a power-source voltage in an integrated circuit. SOLUTION: There are provided a detection cell 4 at a specified position on a power-source line 3 in a semiconductor integrated device 10 and detects a power-source voltage at the position, a detection circuit 7 for detecting, a drop of the power-source voltage detected by the detection cell 4, and a connection wiring 6 which connects the detection cell 4 to the detection circuit 7 and outputs the power-source voltage detected by the detection cell 4 to the detection circuit 7.
