BEAR-FP is a macrocell-based layout system which builds on its predecessor, the BEAR system. It uses BEAR's dynamic and efficient data representation, which unifies topological and geometrical information, and BEAR's routing system. BEAR-FP, however, has a new floorplanning procedure with integrated global routing and hierarchical pin assignment, a new Steiner-tree global router, a detailed channel pin arrangement procedure, and a timing-driven clustering and placement capability. BEAR-FP supports traditional macro-cell layout with routing channels as well as channel-free layout style.

This manual describes the BEAR-FP system in three sections. In section 1, installation instructions and a detailed explanation of the user interface are given, as well as a step-by-step example to help users get started. Clustering, floorplanning, pin assignment, and shape optimization are described in Section II. Although this part of the system is fully automated, the set of parameters and graphic display features provided allow the user to tailor the results to suit their individual needs. In Section III, routing and spacing processes are discussed. While we provide a set of operations (or mechanisms), users have the freedom to choose when and how to apply them. The appendices contain descriptions of the various data files BEAR-FP relies on.
