Integrating Structural Design and Formal Methods in RealTime System Design

Formal methods have been advocated as one of those techniques that can produce highquality software and hardware systems that has been demonstrated to come in ontime, within budget, and satisfy procurer requirements. They are, however, perceived to be difficult to use and unsuitable for presentation to nonspecialists. In addition, they have been criticized for paying too little attention to the system development process.

1. INTRODUCTION

There is a saying in real estate; when land get expensive, multi-storied buildings are the alternative solution. We have a similar situation in the chip industry. For the past thirty years, chip designers have considered whether building integrated circuits multiple layers might create cheaper, more powerful chips.

Performance of deep-sub micrometer very large scale integrated (VLSI) circuits is being increasingly dominated by the interconnects due to increasing wire pitch and increasing die size. A ....etc

Design Patterns


A pattern is a proven solution to a problem in a context.
Christopher Alexander says each pattern is a three-part rule which expresses a relation between a certain context, a problem, and a solution.
Design patterns represent a solutions to problems that arise when developing software within a particular context.
i.e Patterns = problems.solution pairs in a context

Common Emitter BJT Amplifier Design Current Mirror Design


Some Random Observations
● Conditions for stabilized voltage source biasing
● Emitter resistance, RE, is needed.
● Base voltage source will have finite resistance, RB.
● needs to be much larger than RB.
● Small RB - relative to RS - will attenuate input signal.
● Larger RE permits larger RB, but results in lower gain.
● Gain = -RC/RE for RE >> re.
● Split RE with bypassing increa ....etc

1. INTRODUCTION

With the proliferation of portable electronic devices, power efficient data transmission has become increasingly important. For serial data transfer, universal asynchronous receiver / transmitter (UART) circuits are often implemented because of their inherent design simplicity and application specific versatility. Components such as laptop keyboards, palm pilot organizers and modems are few examples of devices that employ UART circuits. In this work, design and analysis of a robust UART architecture has been carried out to m ....etc

Design Of Cluster Logical Volume Manager

Abstract :

In an open systems environment, logical volume manager (LVM) virtualizes storage by consolidating physical storage into logical volumes, which are available to applications or file systems. LVMs are available on most Unix platforms (including Linux) and on Windows 2000. By assembling virtual storage volumes out of numerous physical devices, you can create storage configurations tuned for specific applications, without the limitations of specific hardware devices. Instead, you can make ....etc

ABSTRACT
Many system-on-chip (SoC) integrated circuits contain embedded cores with different scan frequencies. To better meet the test requirements for such heterogeneous SoCs, leading tester companies have recently introduced port-scalable testers, and Many IP core design software like Xilinx, Leonardo Spectrum, and Modelsim etc which can used to design ip core like DMA ,Interrupt Controller etc .These Ip core can be Power aware an Implement on soc by choosing different design tech ....etc
