Standard cell initial placement strategy
A standard cell initial placement strategy was developed that incorporates characteristics of both the class of algorithms that is constructive in nature (i.e., bottom-up) and the class that utilizes a top-down partitioning scheme. This approach was pursued recognizing the fact that while both of these types of algorithms exhibit some rather adverse traits both also possess advantageous properties. Specifically, the placement strategy described incorporates both the simplicity of constructive placement methods and the global connectivity information characteristic of placement schemes involving partitioning. The specified algorithm was implemented within the microelectronics computer-aided design facility at Sandia National Laboratories.
