The sections of respective sections C11-C54 are divided respectively into rectangular line split parts so as to have prescribed width in the X-axis and Y-axis directions. Measurement points are sequentially connected in the order of the route toward the reverse direction alternately at the line split parts to estimate a potential measurement path in the first and second sections.  Simulation period is analyzed for the potential measurement paths, so that the smaller measurement period is determined as the measuring paths within the respective sections.

Abstract: PURPOSE:To reduce greatly the power consumption by inactivating an output drive transistor by the signal given from a signal generating circuit of the preceding stage before an output load transistor of a signal generating circuit of the next stage is activated. CONSTITUTION:An node N201, i.e., the output of the delay part of a signal generating circuit 21 of the preceding stage is connected to the gate of a drive transistor MOSTR Q220 of the output driver of a signal generating circuit of the next stage.
