4.4. Behavioral Model 28Figure 4.7: Calculation of Setup Time4.4.2.1 Leakage PowerFor a fixed supply voltage, gate leakage is approximately fixed and is very less comparedto sub-threshold leakage. Junction leakage is also very less compared to sub-thresholdleakage. Sub-threshold leakage depends on the input combination of the cell. For example,For 2 input NAND gate, leakage will be least when both inputs are at logic level 0and will be most when both the inputs are at logic level 1. Thereby for exact leakagepower calculation, we should characterize the cell for all the input combinations.4.4.2.2 Dynamic PowerDynamic power arises because of switching of the load. This depends on the output loadcapacitance and input transition time. In standard cell library, dynamic power is definedin table lookup form for different values of input transition and output load capacitance.Same methodology is used to calculate power for in-between point of the variable.The characterized Clocked Inverter flip-flop has the resulting data in the form of followinglines.c e l l (DFF_new) {2 area : 3 1 . 8 4 ;c e l l _ f o o t p r i n t : "QDFF" ;4 f f ( IQ , IQN) {next_state : "D" ;6 clocked_on : "CK" ;}
