Abstract: Apparatus, methods, and computer readable code for computing parameters related to layout schemes of integrated circuits are disclosed herein. In some embodiments, an actual layout scheme is computed, for example, for a netlist. In some embodiments, one o or more layout schemes are scored based on, for example, susceptibility to failure and/or yield in manufacturing.

Abstract: A method of designing a single-chip circuit system that includes several dissimilar (digital, analog, memory, power, RF, electro-optical) modules, and the system so designed. A prior art method is used for an initial design of the system, including signal and power conductors connecting the modules. Signal conductors are initially designed for current densities in a first range. Power conductors are initially designed for current densities in a second range. For each signal conductor, an initial value of a design parameter is changed to increase the current density into a higher third range, the resistance of the conductor is reduced, and the parameter value is restored to its initial value. For each power conductor, an initial value of a design parameter is changed to decrease the current density into a lower fourth range, the resistance of the conductor is increased, and the parameter value is restored to its initial value.
