隨著集成電路頻率的提高和多核時代的到來，傳統的高速電互連技術面臨著越來越嚴重的瓶頸問題，而高速下的光互連具有電互連無法比擬的優勢，成為未來電互連的理想替代者，也成為科學研究的熱點問題。目前，由OIF(Optical Intemetworking Forum，光網絡論壇)論壇提出的甚短距離光互連協議，主要面向主干網，其延遲、功耗、兼容性等都不能滿足板間、芯片間光互連的需要，因此，研究定制一種適用于板級、芯片級的光互連協議具有非常重要的研究意義。 本論文將協議功能分為數據鏈路層和物理層來設計，鏈路層功能包括了協議原語設計，數據幀格式和數據傳輸流程設計，流量控制機制設計，協議通道初始化設計，錯誤檢測機制設計和空閑字符產生、時鐘補償方式設計；物理層功能包含了數據的串化和解串功能，多通道情況下的綁定功能，數據編解碼功能等。 然后，文章采用FPGA(Field Programmable Gate Array,現場可編程門陣列)技術實現了定制協議的單通道模式。重點是數據鏈路層的實現，物理層采用定制具備其功能的IP(Intellectual Property,知識產權)——RocketIO來實現。實現的過程中，采用了Xilinx公司的ISE(Integrated System Environment,集成開發環境)開發流程，使用的設計工具包括:ISE，ModelSim，Synplify Pro,ChipScope等。 最后，本文對實現的協議進行了軟件仿真和上扳測試，訪真和測試結果表明，實現的單通道模式，支持的最高串行頻率達到3.5GHz，完全滿足了光互連驗證系統初期的要求，同時由RocketIO的高速串行差分口得到的眼圖質量良好，表明對物理層IP的定制是成功的。

Radio Frequency Integrated Circuit Design
I enjoyed reading this book for a number of reasons. One reason is that itaddresses high-speed analog design in the context of microwave issues. This isan advanced-level book, which should follow courses in basic circuits andtransmission lines. Most analog integrated circuit designers in the past workedon applications at low enough frequency that microwave issues did not arise.As a consequence, they were adept at lumped parameter circuits and often notcomfortable with circuits where waves travel in space. However, in order todesign radio frequency (RF) communications integrated circuits (IC) in thegigahertz range, one must deal with transmission lines at chip interfaces andwhere interconnections on chip are far apart. Also, impedance matching isaddressed, which is a topic that arises most often in microwave circuits. In mycareer, there has been a gap in comprehension between analog low-frequencydesigners and microwave designers. Often, similar issues were dealt with in twodifferent languages. Although this book is more firmly based in lumped-elementanalog circuit design, it is nice to see that microwave knowledge is brought inwhere necessary.Too many analog circuit books in the past have concentrated first on thecircuit side rather than on basic theory behind their application in communications.The circuits usually used have evolved through experience, without asatisfying Intellectual theme in describing them. Why a given circuit works bestcan be subtle, and often these circuits are chosen only through experience. Forthis reason, I am happy that the book begins first with topics that require anIntellectual approach—noise, linearity and filtering, and technology issues. Iam particularly happy with how linearity is introduced (power series). In therest of the book it is then shown, with specific circuits and numerical examples,how linearity and noise issues arise.

In the past decade, the size and complexity of manyFPGA designs exceeds the time and resourcesavailable to most design teams, making the use andreuse of Intellectual Property (IP) imperative.However, integrating numerous IP blocks acquiredfrom both internal and external sources can be adaunting challenge that often extends, rather thanshortens, design time. As today's designs integrateincreasing amounts of functionality, it is vital thatdesigners have access to proven, up-to-date IP fromreliable sources.

SRAM-based FPGAs are non-volatile devices. Upon powerup, They are required to be programmed from an external source. This procedure allows anyone to easily monitor the bit-stream, and clone the device. The problem then becomes how can you effectively protect your Intellectual property from others in an architecture where the part is externally programmed?
