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

随着新研发单板上高速Serdes信号的增多，信号完整性测试显的越来越重要，本文档围绕Serdes信号的眼图抖动测试总结一些测试注意事项。新研发单板上高速Serdes信号速率高达2.45G，一些时钟信号上升/下降沿达到400ps左右，必然需要测量Serdes信号的眼图、抖动，在这里总结一些测试经验和注意事项。UBPG1单板上有如下几种高速数据SERDES信号：1. GE SERDES接口(SGMII接口标准)2. AIF SERDES接口(CPRI接口标准)3. IQ SERDES接口(类CPRI接口标准，自定义帧格式)4. 光口 SERDES接口(CPRI接口标准)对于SERDES信号，其信号电气特性由IEEE协议规定，在协议中会给出相应的眼图测试模板及抖动指标，部分芯片厂家会在DATASHEET中给出单独的眼图测试模板及抖动指标（一般会比协议要求的更宽松）。UBPG1单板上的SERDES接口按电气特性分有两种，一种是SGMII接口（用1000-BASE-CX模板，IEEE协议39节）；一种是CPRI接口（用XAUI模板，IEEE协议49节）。
