Fixed-outline floorplanning in very large scale integration
Abstract
Traditional floorplanning handles packaging in order to minimize the chip area. However, the floorplanning of the modern very large scale integrated circuit (VLSI) usually needs to put each module in the fixed boundary, also taking into account each module of the placement and linked to each other even constraints. The fixed-outline floorplanning is one of the most challenging problems in modern floorplanning, because it requires the simultaneous consideration of the constraints of the interconnection and module positions.
In this paper, I study the problem of modern plan layout: the fixed boundary layout planning, I focus on the simulated annealing algorithm (SA) of the B*-tree plan for the planar layout. For the simulated annealing algorithm, we will first with the analogy to physical annealing leads to the introduction of the simulated annealing algorithm, and then introduces the problems involved in the layout planning of simulated annealing algorithm, focus on understanding the calculation process of simulated annealing algorithm and use of the related variables. For B*-tree, this paper mainly introduces the representation method and the plane layout algorithm based on B*-tree. An improved simulated annealing (MSA) algorithm is proposed for the fixed shape layout, and compared with the advantages of the original simulated annealing algorithm.
