    摘要： In a method of estimating a leakage current in a 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 a cell is generated by arithmetically operating actual leakage characteristic functions. A segment leakage characteristic function of a segment is generated by arithmetically operating the virtual cell leakage characteristic functions of all cells in the segment. Then, a full chip leakage characteristic function of the chip is generated by statistically operating the segment leakage characteristic functions of all segments in the chip. Accordingly, computational loads of Wilkinson's method for generating the full chip leakage characteristic function can remarkably be reduced.

    摘要： An impulse generation circuit is provided for generating an impulse using a transmission line. Impulse characteristics of the impulse generation circuit are varied with the length of a transmission line rather than the characteristic variation of various devices used therein. The length of the transmission line is adjusted, such that a width of a generated pulse is adjusted. Because an end of the transmission line is short-circuited, the transmission line length can be easily adjusted on a substrate, and a ringing phenomenon due to re-reflection can be removed using termination impedance.
