Accuracy

Wave forms of current before and after the reduction are compared at some edges in the circuit. The results are shown in Figure 1, Figure 2 and Figure 3 using the display tool 'awaves'. Each figure consists of three graphs. The upper-most graph shows the wave form of the entire simulation time span. The lower two graphs are the magnification at two time points when current value changes much. It seems that the error is within permissible level to designers.
