In a VLSI layout design using the building block approach, the design is divided into two phases, placement and routing. On the other hand, a new hierarchical floorplanning method was proposed by Dai et al., in which a global routing for the evaluation of the placement is determined ...
As the technology advances in the field of VLSI physical design at rapid pace, there is a demand to incorporate the maximum number of transistors and modules within the relatively minimum area. Generally reduction of silicon chip area is the goal and objective of the Placement in Physical Design...
Floorplanning in very large scale integrated-circuit (VLSI) design is the first phase in the process of designing the physical layout of a chip. This makes the floorplanning problem of paramount importance, since it determines the performance, size, yield, and reliability of VLSI chips [1]. ...
Floorplanning is a critical step in the physical design of VLSI circuits. The floorplanning optimization problem can be formulated as a global optimization problem minimizing wire length, with the area of each rectangular module fixed while the module's height and width are allowed to vary subject...
Routability optimization has become the major concern in floorplanning. In traditional floor planners, area minimization is an important issue. Due to the recent advances in VLSI technology, interconnect has become a dominant factor to the overall performance of a circuit. Routability prediction is thu...
