Motivation: As the human genome project progresses and some microbial and eukaryotic genomes are recognized, numerous biotechnological processes have attracted increasing number of biologists, bioengineers and computer scientists recently. Biotechnological processes profoundly involve production and analysis of highthroughput experimental data. Numerous sequence libraries of DNA and protein str...

This research aims to provide a deeper understanding of the unique features of CAD/CAM media tools and their applications. Moreover, it analyzes the role of the CAD/CAM media in the fabricating of physical models and the kind of added benefits they offer above and beyond those of traditional handmade physical models. This research concludes that certain aspects of CAD/CAM can aid in the digital...

This paper suggests the automated programming of CNC-machine tools with the help of artificial intelligence. Based on a CAD-model of the product, the system, without any help from an expert, automatically prepares a CNC program, so that the machining is safe, accurate and time-efficient. The developed CAD/CAM system uses NSGA-II multi-objective optimisation and swarm intelligence. The system co...

Typical complex systems that involve microsensors and microactuators exhibit heterogeneity both at the implementation level and the problem level. This naturally leads to a heterogeneous approach to system design that uses domain-specific models of computation (MoC) at various levels of abstractions to define a system, and leverages multiple CAD tools to do simulation, verification, and synthes...

The NVAX CPU chip is a 1.3 million transistor, VAX microprocessor designed in Digital's 0.75-micrometer CMOS-4 technology. It has a typical cycle time of 12 ns under worst-case operating conditions. The goal of the chip design team was to design a high-performance, robust, and reliable chip, within the constraints of a short schedule. Design strategies were developed to achieve this goal, inclu...

Standard static CMOS logic is responding to the requirement of high frequency and low power of digital systems. However, the digital switching noise generated by this logic is not suited for the design of performance mixedsignal integrated systems. In mixed-signal application the analog functionality can be affected by this digital switching noise and therefore resolution is degraded. The Curre...

Power consumption is rapidly becoming an area of growing concern in IC and system design houses. Issues such as battery life, thermal limits, packaging constraints and cooling options are becoming key factors in the success of a product. As a consequence, IC and system designers are beginning to see the impact of power on design area, design speed, design complexity and manufacturing cost. Whil...

This paper describes the application of CLP (constraint logic programming) to several digital circuit design problems. It is shown that logic programming together with efficient constraint propagation techniques is an adequate programming environment for complex real world problems like high level synthesis, simulation, code generation, and memory synthesis. Different types of constraints Boole...

In this paper we survey major problems faced by EDA tools in tackling deep submicron (DSM) design challenges like: crosstalk, reliability, power, and interconnect dominated delay. We discuss the need for rethinking quality models used in EDA tools to allow early and reliable planning, estimation, analysis, and optimization. Key design quality metrics from a CAD tool perspective are surveyed, an...

The growing importance of VLSI is getting much attention. But the increasing complexity of VLSI also creates lots of problems for the computer scientists to work on. If there is no other new way to help the designers, the whole design process will get more difficult to maintain. That's the need for an object-oriented (OO) design framework for CAD world. Not only to develop new methods is needed...
