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.
