Abstract
A circuit design process for the reduction of routing congestion is described. This process includes a block placement operation, an initial pin optimization for the block placement, and global routing based upon the initial pin optimization. Congestion data is generated from the global routing and, in an automated process, the pins are re-optimized, based upon the congestion data. This process can be used as part of a custom layout design process, for example.
