Methods, algorithms, software, architectures and system for placing clocked components and routing timing signals in a circuit and/or layout

摘要

A method, algorithm, software, architecture and system for placing circuit components and routing wires. The method and algorithm generally include (a) placing components in an array of allowed locations, wherein each of the components receives a clock signal and each of the allowed locations is about the same distance from a first nearest neighbor along at least a first axis as are other allowed locations along said first axis, and (b) one of the following: (i) independently routing a plurality of combinational paths from at least two components to at least two other components, (ii) routing the clock signal to the components, or both (i) and (ii). The present method, algorithm, software, architecture and system advantageously reduce power and/or current consumption in integrated circuits, improve uniformity of timing for signal paths between clocked circuit components, and/or ensure that timing requirements for signal paths between clocked circuit components are met automatically.
