    摘要： A power gating circuit includes a logic circuit, a switching element and a retention flip-flop. The logic circuit is coupled between a first power rail and a virtual power rail. The switching element selectively couples the virtual power rail to a second power rail in response to a mode control signal indicating an active mode or a standby mode. The retention flip-flop selectively performs a flip-flop operation or a data retention operation in response to a voltage of the virtual power rail.

    摘要： In a method of estimating a leakage current in semiconductor device, a chip including a plurality of cells is divided into segments by a grid model. Spatial correlation is determined as spatial correlation between process parameters concerned with the leakage currents in each of the cells. A virtual cell leakage characteristic function of the cell is generated by arithmetically operating actual leakage characteristic functions. A segment leakage characteristic function is generated by arithmetically operating the virtual cell leakage characteristic functions of each cell in the segment. Then, a full chip leakage characteristic function is generated by statistically operating the segment leakage characteristic functions of each segment in the chip. Accordingly, the computational loads of Wilkinson's method for generating the full chip leakage characteristic function may be remarkably reduced.
