چکیده

In this paper, a new construct called connection graph, Gc, is proposed. An efficient geometric algorithm for constructing Gc is given. We present a framework for designing a class of time and space efficient maze-running and line-search rectilinear shortest path and rectilinear minimum spanning tree algorithms based on Gc. We give several example maze-running and line-search algorithms based on Gc to demonstrate the power of Gc in designing good sequential VLSI routing algorithms.

An Optimization Algorithm Based on Grid-graphs for Minimizing Interconnect Delay in Vlsi Layout Design

In this paper, we describe a routing optimization algorithm based on grid-graphs for application in a deep-submicron VLSI layout design. The proposed algorithm, named S-RABILA (for Simultaneous Routing and Buffer Insertion with Look-Ahead), constructs a maze routing path, simultaneously with buffer insertion and wire sizing, taking into account wire and buffer obstacles, such that the interconn...

Recent Trends in the Application of Meta-Heuristics to VLSI Layout Design

This paper browses through some well-known meta-heuristic search strategies, and briefly discusses some of their recent applications to the VLSI layout design process. It starts with very brief description of the different phases of VLSI layout design, and a brief overview of Meta-Heuristic search strategies. Since most of the VLSI layout design problems are hard optimization problems, the conc...

A Continuous Plane Model to Machine Layout Problems Considering Pick-Up and Drop-Off Points: An Evolutionary Algorithm

One of the well-known evolutionary algorithms inspired by biological evolution is genetic algorithm (GA) that is employed as a robust and global optimization tool to search for the best or near-optimal solution with the search space. In this paper, this algorithm is used to solve unequalsized machines (or intra-cell) layout problems considering pick-up and drop-off (input/output) points. Such p...

An Efficient Genetic Algorithm for Task Scheduling on Heterogeneous Computing Systems Based on TRIZ

An efficient assignment and scheduling of tasks is one of the key elements in effective utilization of heterogeneous multiprocessor systems. The task scheduling problem has been proven to be NP-hard is the reason why we used meta-heuristic methods for finding a suboptimal schedule. In this paper we proposed a new approach using TRIZ (specially 40 inventive principles). The basic idea of thi...
