Method and System for Adaptive Physical Design

A design system comprising:

• means for performing a free placement of a system design comprising a plurality of power domains, wherein the power domains are not constrained to physical regions;
• means for assigning a physical region to each of the power domains based on the free placement of cells in the power domains;
• means for performing a soft cluster placement of the system design with each power domain and corresponding physical region defined as a soft cluster;
• means for refining at least one physical region based on the soft cluster placement;
• means for redefining cells in at least one power domain based on the soft cluster placement of the cells and the corresponding physical region;
• and
• means for performing a hard cluster placement of the system design with each power domain and corresponding physical region defined as a hard cluster to generate final power domains.

A computer readable medium storing instructions that, when executed by a processor of a computer system, cause the computer system to perform a method comprising:

• performing a free placement of a system design comprising a plurality of power domains, wherein the power domains are not constrained to physical regions;
• assigning a physical region to each of the power domains based on the free placement of cells in the power domains;
• performing a soft cluster placement of the system design with each power domain and corresponding physical region defined as a soft cluster;
• refining at least one physical region based on the soft cluster placement;
• redefining cells in at least one power domain based on the soft cluster placement of the cells and the corresponding physical region;
• and
• performing a hard cluster placement of the system design with each power domain and corresponding physical region defined as a hard cluster to generate final power domains.
