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.

《計算機操作系統課程設計》教學大綱
課程名稱：計算機操作系統 學時（周）：10 學分：1
課程英文名稱：operating System of computer 課程類別：專業基礎課
適用專業：計算機科學與技術、軟件工程
一、課程設計的目的
操作系統課程設計是操作系統課程的重要實踐性環節。通過課程設計，可以加深學生對課堂中所講授內容的理解，培養學生的系統開發能力，加強學生的項目經驗，使學生初步具有研究、設計、編制和調試操作系統模塊的能力。
二、課程設計方式
1、課程設計題目的選定
采用指導教師提供參考題目學生自行選定課程設計題目。每2~3人為一組，但課程設計報告不得雷同，否則判定成績為0。
2、課程設計任務的完成
在指導教師的指導下，每組學生共同完成課題的分析，并做好分工，在此基礎上完成自己那部分工作的設計、代碼編寫和調試，獨立撰寫課程設計報告。所有工作任務主要在實驗室完成。
三、基本要求
課程設計教學方法：主要以學生上機操作為主，教師指導為輔
課程設計要求：
1、對系統進行功能分解、模塊分析、控制模塊分析正確
2、選擇合適的操作系統原理所需要數據結構以及相應的算法
3、程序規模適中，盡可能的使系統的功能更加完善和全面
4、掌握程序調試的方法
5、說明書、流程圖要清楚，闡明設計思路。
6、撰寫課程設計報告。按格式要求寫出完整、規范的報告并打印。其中模塊圖、流程圖要清楚、規范。

Communication today is not as easy as it was in the past. Protecting numerous com-
munication services, which are operating in the same or adjacent communication
channels, has become increasingly challenging. Communication systems have to be
protected from both natural and manmade interference. Electromagnetic interfer-
ence can be radiated or conducted, intentional or unintentional.

Microwave radio network design is a subset of activities that constitute
the overall transmission network design. Transmission networks are
sometimes called transport networks, access networks, or connectivity
networks. For many wireless carriers, microwave is becoming a popu-
lar preference over wireline (leased lines) transport for many reasons,
especially as microwave radio equipment costs decrease and installation
becomes simpler. Low monthly operating costs can undercut those of
typical single (and especially multiple) T1/E1 expenses, proving it to be
more economical over the long term—usually two to four years. Network
operators also like the fact that they can own and control microwave
radio networks instead of relying on other service providers for network
components.

Soon after Samuel Morse’s telegraphing device led to a deployed electri-
cal telecommunications system in 1843, waiting lines began to form by those
wanting to use the system. At this writing queueing is still a significant factor in
designing and operating communications services, whether they are provided
over the Internet or by other means, such as circuit switched networks.

The need to develop reliable microelectronic devices capable of operating at high
speeds with complex functionality requires a better understanding of the factors
that govern the thermal performance of electronics. With an increased demand
on system reliability and performance combined with miniaturization of the
devices, thermal consideration has become a crucial factor in the design of elec-
tronic packages, from chip to system levels.
