This book has grown out of my teaching and research at the University of Surrey and out of my previous experiences in companies such as Philips, Ascom and Motorola. It is primarily intended for use by students in master’s level and enhanced final-year under- graduate courses who are specialising in communication systems and wish to understand the principles and current practices of the wireless communication channel, including both antenna and propagation aspects

This is believed to be the first book that takes a view of nanotechnology from a telecommunications and networking perspective. Nanotechnology refers to the manip- ulation of materials at the atomic or molecular level. Nanotechnology is getting a lot of attention of late not only in academic settings and in laboratories around the world, but also in government and venture capitalists’ initiatives. There now is a major drive to commercialize the technology by all sorts of firms, ranging from start- ups to Fortune 100 companies.

This book provides a comprehensive overview of the technology behind the pico-solar revolution and offers guidance on how to test and choose quality products. The book also discusses how pioneering companies and initiatives are overcoming challenges to reach scale in the market- place, from innovative distribution strategies to reach customers in rural India and Tanzania, to product development in Cambodia, product assembly in Mozambique and the introduction of ‘pay as you go’ technology in Kenya.

本文主要介紹如何在Wado設(shè)計套件中進行時序約束，原文出自 xilinx中文社區(qū)。1 Timing Constraints in Vivado-UCF to xdcVivado軟件相比于sE的一大轉(zhuǎn)變就是約束文件，5E軟件支持的是UcF（User Constraints file，而 Vivado軟件轉(zhuǎn)換到了XDc（Xilinx Design Constraints）。XDC主要基于SDc（Synopsys Design Constraints）標準，另外集成了Xinx的一些約束標準可以說這一轉(zhuǎn)變是xinx向業(yè)界標準的靠攏。Altera從 TimeQuest開始就一直使用SDc標準，這一改變，相信對于很多工程師來說是好事，兩個平臺之間的轉(zhuǎn)換會更加容易些。首先看一下業(yè)界標準SDc的原文介紹：Synopsys widely-used design constraints format, known as sDc, describes the design intent"and surrounding constraints for synthesis, clocking, timing, power, test and environmental and operating conditions. sDc has been in use and evolving for more than 20 years, making it the most popular and proven format for describing design constraints. Essentially all synthesized designs use SDc and numerous EDa companies have translators that can read and process sDc
