Design techniques for electronic systems areconstantly changing. In industries at the heart of thedigital revolution, this change is especially acute.Functional integration, dramatic increases incomplexity, new standards and protocols, costconstraints, and increased time-to-market pressureshave bolstered both the design challenges and theopportunities to develop modern electronic systems.One trend driving these changes is the increasedintegration of core logic with previously discretefunctions to achieve higher performance and morecompact board designs.

In this paper, we discuss efficient coding and design styles using verilog. This can beimmensely helpful for any digital designer initiating designs. Here, we address different problems rangingfrom RTL-Gate Level simulation mismatch to race conditions in writing behavioral models. All theseproblems are accompanied by an example to have a better idea, and these can be taken care off if thesecoding guidelines are followed. Discussion of all the techniques is beyond the scope of this paper, however,here we try to cover a few of them.

波長信號(hào)的解調(diào)是實(shí)現(xiàn)光纖光柵傳感網(wǎng)絡(luò)的關(guān)鍵，基于現(xiàn)有的光纖光柵傳感器解調(diào)方法，提出一種基于FPGA的雙匹配光纖光柵解調(diào)方法，此系統(tǒng)是一種高速率、高精度、低成本的解調(diào)系統(tǒng)，并且通過引入雙匹配光柵有效地克服了雙值問題同時(shí)擴(kuò)大了檢測范圍。分析了光纖光柵的測溫原理并給出了該方案軟硬件設(shè)計(jì)，綜合考慮系統(tǒng)的解調(diào)精度和FPGA的處理速度給出了基于拉格朗日的曲線擬合算法。 Abstract: Sensor is one of the most important application of the fiber grating. Wavelength signal demodulating is the key techniques to carry out fiber grating sensing network， based on several existing methods of fiber grating sensor demodulation inadequate， a two-match fiber grating demodulation method was presented. This system is a high-speed， high precision， low-cost demodulation system. And by introducing a two-match grating effectively overcomes the problem of double value while expands the scope of testing. This paper analyzes the principle of fiber Bragg grating temperature and gives the software and hardware design of the program. Considering the system of demodulation accuracy and processing speed of FPGA，this paper gives the curve fitting algorithm based on Lagrange.

Addressbook using double-linked list. This example shows the use of a double-linked list by implementing an addressbook for the console. It has features like inserting, searching(linear), sorting(bubble sort), deleting and load/save to a file. I wrote this during my study of Applied Computer Science so it s intended mainly for students who want to know about some advanced programming techniques in C. The Code was compiled with MSVC++ 6.0 but it should compile with any ANSI-compliant compiler.
