A system for parallelizing software in computer-aided design (CAD) software for circuit design includes a computer. The computer is configured to form or optimize a plurality of clusters in parallel. Each cluster in the plurality of clusters includes a set of nodes in a netlist in a design. The computer is configured to determine placements for blocks in a netlist in parallel, based on iterative improvement, partitioning, or analytic techniques.

Apparatus and associated methods for parallelizing clustering and placement

A method for designing a system on a target device includes performing delay annotation where a first delay associated with a first aspect of the system is determined by a first software thread and a second delay associated with a second aspect of the system is determined by a second software thread and the first and second software threads operate in parallel. Ensuring independence between each aspect of the system will facilitate efficient parallelism (i.e. minimal synchronization) while still maintaining serial equivalency.

Method and apparatus for performing delay annotation

A method of performing placement of resources in a computer-aided design (CAD) tool includes performing a first congestion analysis, proposing a placement move, and evaluating the placement move. The method further includes incrementally updating information used for performing another congestion analysis.
