Abstract
A method of inserting repeaters into a complex integrated circuit includes the step of selecting, based upon signal transition data, a maximum wire length to be positioned between two repeaters in a complex integrated circuit. The maximum wire length is then correlated with a signal transition-based ratio coefficient defining the relation between a signal transition time and a Resistive-Capacitive delay. A signal transition-based Resistive-Capacitive delay is then defined based upon the signal transition-based ratio coefficient. A repeater distribution is then mapped within the complex integrated circuit based upon the signal transition-based Resistive-Capacitive delay.
