Abstract: Designers who must interface 1-Wire temperature sensors with Xilinx field-programmable gate arrays(FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable softwarementioned in this document can also be used as a starting point to connect other 1-Wire slave devices. The systemimplements a 1-Wire master connected to a UART and outputs temperature to a PC from the DS28EA00 temperaturesensor. In addition, high/low alarm outputs are displayed from the DS28EA00 PIO pins using LEDs.
Abstract: This application note discusses the development and deployment of 3G cellular femtocell base stations. The technicalchallenges for last-mile residential connectivity and adding system capacity in dense urban environments are discussed, with 3Gfemtocell base stations as a cost-effective solution. Maxim's 3GPP TS25.104-compliant transceiver solution is presented along withcomplete radio reference designs such as RD2550. For more information on the RD2550, see reference design 5364, "FemtocellRadio Reference Designs Using the MAX2550–MAX2553 Transceivers."
The LogiCORE™ GTP Wizard automates the task of creating HDL wrappers to configure the high-speed serial GTP transceivers in Virtex™-5 LXT and SXT devices. The menu-driven interface allows one or more GTP transceivers to be configured using pre-definedtemplates for popular industry standards, or from scratch, to support a wide variety of custom protocols.The Wizard produces a wrapper, an example design, and a testbench for rapid integration and verification of the serial interface with your custom function
Features• Creates customized HDL wrappers to configureVirtex-5 RocketIO™ GTP transceivers• Users can configure Virtex-5 GTP transceivers toconform to industry standard protocols usingpredefined templates, or tailor the templates forcustom protocols• Included protocol templates provide support for thefollowing specifications: Aurora, CPRI, FibreChannel 1x, Gigabit Ethernet, HD-SDI, OBSAI,OC3, OC12, OC48, PCI Express® (PCIe®), SATA,SATA II, and XAUI• Automatically configures analog settings• Each custom wrapper includes example design, testbench; and both implementation and simulation scripts

要求越來越嚴格，這勢必對用于大規模集成電路設計的EDA 工具提出越來越高的
要求。自1972 年美國加利福尼亞大學柏克萊分校電機工程和計算機科學系開發
的用于集成電路性能分析的電路模擬程序SPICE（Simulation Program with IC
Emphasis）誕生以來，為適應現代微電子工業的發展，各種用于集成電路設計的
電路模擬分析工具不斷涌現。HSPICE 是Meta-Software 公司為集成電路設計中
的穩態分析，瞬態分析和頻域分析等電路性能的模擬分析而開發的一個商業化通
用電路模擬程序，它在柏克萊的SPICE（1972 年推出），MicroSim公司的PSPICE
（1984 年推出）以及其它電路分析軟件的基礎上，又加入了一些新的功能，經
過不斷的改進，目前已被許多公司、大學和研究開發機構廣泛應用。HSPICE 可
與許多主要的EDA 設計工具，諸如Candence,Workview 等兼容，能提供許多重要
的針對集成電路性能的電路仿真和設計結果。采用HSPICE 軟件可以在直流到高
于100MHz 的微波頻率范圍內對電路作精確的仿真、分析和優化。在實際應用中，
HSPICE能提供關鍵性的電路模擬和設計方案，并且應用HSPICE進行電路模擬時，
其電路規模僅取決于用戶計算機的實際存儲器容量。
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.
