  • Xilinx UltraScale:新一代架构满足您的新一代架构需求(EN)

      中文版详情浏览:http://www.elecfans.com/emb/fpga/20130715324029.html   Xilinx UltraScale:The Next-Generation Architecture for Your Next-Generation Architecture    The Xilinx® UltraScale™ architecture delivers unprecedented levels of integration and capability with ASIC-class system- level performance for the most demanding applications.   The UltraScale architecture is the industr y's f irst application of leading-edge ASIC architectural enhancements in an All Programmable architecture that scales from 20 nm planar through 16 nm FinFET technologies and beyond, in addition to scaling from monolithic through 3D ICs. Through analytical co-optimization with the X ilinx V ivado® Design Suite, the UltraScale architecture provides massive routing capacity while intelligently resolving typical bottlenecks in ways never before possible. This design synergy achieves greater than 90% utilization with no performance degradation.   Some of the UltraScale architecture breakthroughs include:   • Strategic placement (virtually anywhere on the die) of ASIC-like system clocks, reducing clock skew by up to 50%    • Latency-producing pipelining is virtually unnecessary in systems with massively parallel bus architecture, increasing system speed and capability   • Potential timing-closure problems and interconnect bottlenecks are eliminated, even in systems requiring 90% or more resource utilization   • 3D IC integration makes it possible to build larger devices one process generation ahead of the current industr y standard    • Greatly increased system performance, including multi-gigabit serial transceivers, I/O, and memor y bandwidth is available within even smaller system power budgets   • Greatly enhanced DSP and packet handling   The Xilinx UltraScale architecture opens up whole new dimensions for designers of ultra-high-capacity solutions.

  • Rf And Microwave Power Amplifier Design(2005)

    The main objective of this book is to present all the relevant informationrequired for RF and micro-wave power amplifier design includingwell-known and novel theoretical approaches and practical design techniquesas well as to suggest optimum design approaches effectively combininganalytical calculations and computer-aided design. This bookcan also be very useful for lecturing to promote the analytical way ofthinking with practical verification by making a bridge between theoryand practice of RF and microwave engineering. As it often happens, anew result is the well-forgotten old one. Therefore, the demonstrationof not only new results based on new technologies or circuit schematicsis given, but some sufficiently old ideas or approaches are also introduced,that could be very useful in modern practice or could contributeto appearance of new ideas or schematic techniques.

    解压密码:www.elecfans.com 随着微电子技术的迅速发展以及集成电路规模不断提高,对电路性能的设计 要求越来越严格,这势必对用于大规模集成电路设计的EDA 工具提出越来越高的 要求。自1972 年美国加利福尼亚大学柏克莱分校电机工程和计算机科学系开发 的用于集成电路性能分析的电路模拟程序SPICE(Simulation Program with IC Emphasis)诞生以来,为适应现代微电子工业的发展,各种用于集成电路设计的 电路模拟分析工具不断涌现。HSPICE 是Meta-Software 公司为集成电路设计中 的稳态分析,瞬态分析和频域分析等电路性能的模拟分析而开发的一个商业化通 用电路模拟程序,它在柏克莱的SPICE(1972 年推出),MicroSim公司的PSPICE (1984 年推出)以及其它电路分析软件的基础上,又加入了一些新的功能,经 过不断的改进,目前已被许多公司、大学和研究开发机构广泛应用。HSPICE 可 与许多主要的EDA 设计工具,诸如Candence,Workview 等兼容,能提供许多重要 的针对集成电路性能的电路仿真和设计结果。采用HSPICE 软件可以在直流到高 于100MHz 的微波频率范围内对电路作精确的仿真、分析和优化。在实际应用中, HSPICE能提供关键性的电路模拟和设计方案,并且应用HSPICE进行电路模拟时, 其电路规模仅取决于用户计算机的实际存储器容量。 The HSPICE Integrator Program enables qualified EDA vendors to integrate their products with the de facto standard HSPICE simulator, HSPICE RF simulator, and WaveView Analyzer™. In addition, qualified HSPICE Integrator Program members have access to HSPICE integrator application programming interfaces (APIs). Collaboration between HSPICE Integrator Program members will enable customers to achieve more thorough design verification in a shorter period of time from the improvements offered by inter-company EDA design solutions.
