چکیده

With resent advances of Deep Sub Micron technologies, the floorplanning problem is an essential design step in VLSI layout design and it is how to place rectangular modules as density as possible. In this paper, we propose a novel constraint driven floorplanning technique based on Genetic Algorithm (GA). Many works have done for the floorplanning problem using GA. However, no studies have ever seen the effect of applying GA in consideration of bus routing constraint and position constraint. Experimental results show improvement of bus routing constraint and position constraint, keeping the chip area and total wire length. Key-Words: Genetic Algorithm, Bus routing, Floorplanning, Constraint-driven, LSI layout

52 . 2 Floorplanning with Alignment and Performance Constraints

In this paper, we present a floorplanning algorithm based on sequence pair representation. Our floorplanner has the following important features: 1) It is explicitly designed for fixed-frame floorplanning, which is different from traditional well-researched minarea floorplanning. Moreover, we also show that it can be adapted to minimize total area. 2) It addresses the problem of handling alignm...

Microarchitectural Floorplanning for Thermal Management : A Technical Report UVA CS TR CS - 2005 - 08

In current day microprocessors, exponentially increasing power densities, leakage, cooling costs, and reliability concerns have resulted in temperature becoming a first class design constraint like performance and power. Hence, virtually every high performance microprocessor uses a combination of an elaborate thermal package and some form of Dynamic Thermal Management (DTM) scheme that adaptive...

Application of Area Predicted TCG Algorithm in Floorplanning with Boundary Constraint

Floorplanning determines the positions of blocks on a chip subject to various objectives. In practical physical design, on the requirement of placing some blocks along the boundaries of the chip such as the blocks can be connected to I/O pads, the floorplanning with boundary constraint is raised. In this paper, we apply a floorplanning algorithm named area predicted transitive closure graphs (A...

Solving a New Multi-objective Inventory-Routing Problem by a Non-dominated Sorting Genetic Algorithm

This paper considers a multi-period, multi-product inventory-routing problem in a two-level supply chain consisting of a distributor and a set of customers. This problem is modeled with the aim of minimizing bi-objectives, namely the total system cost (including startup, distribution and maintenance costs) and risk-based transportation. Products are delivered to customers by some heterogeneous ...
