1.5.1 WIRE LENGTH LOAD
Table 1-1. shows the equivalent standard load matrix for 4-layer and 5-layer
metal interconnect. The equivalent standard load values are function of gate
count and fanout. These values are based on capacitive loading and are used in
wire length estimates which affect propagation delay.
