The complexity of the VLSI physical design flow grows dramatically as the level of integration increases. An effective way to manage this increasing complexity is through the use of regular designs which contain more reusable parts. In this work we introduce HiReg, a new floorplanning algorithm that generates regular floorplans. HiReg automatically extracts repeating patterns in a design by using graph mining techniques. Regularity is exploited by reusing the same floorplan for multiple instances of a pattern, as long as neither area, wire length or existing hierarchy constraints are violated or compromised. The proposed scheme is targeted towards early system-level design of chip multiprocessors (CMPs). Experiments show the scalability of the method for many-core CMPs and competitive results in area and wire length
