METHOD AND APPARATUS FOR AUTOMATIC SYNTHESIS, PLACEMENT, AND ROUTING OF COMPLEX STRUCTURES

The present invention consists of a method and apparatus for the automatic creation of the topology, component sizing, placement, and routing of complex structures, such as electronic circuits or mechanical systems, to satisfy prespecified high-level design goals. The present invention uses a population of entities which are evolved over a series of generations by an iterative process involving the application of operations, such as mutation, crossover, reproduction, and architecture-altering operations. The individuals in the population are each developed, in a developmental process, into a structure that may potentially satisfy the design goals. The present invention also determines the placement of components within the developing structure and determining the routing of the connecting means (wires for electrical circuits) between the components. The behavior of the structures is evaluated in relation to the high-level design goals, and those structures more closely satisfying the design goals are evolved further until a structure is generated that either meets the prespecified design goal. In this manner, the topology, component sizing, placement, and routing of a complex structure may be obtained.
