BonnPlace: Placement of leading-edge chips by advanced combinatorial algorithms
BonnPlace is the placement tool of the University of Bonn, Germany. It is continuously used in the industry for the placement of most complex chips. Global placement is based on quadratic placement and multisection. Legalization of macros and standard cells uses minimum cost flow and dynamic programming algorithms. We describe details of our implementation and present new experimental results.
