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.

Abstract: There are many things to consider when designing a power supply for a field-programmablegate array (FPGA). These include (but are not limited to) the high number of voltage rails, and thediffering requirements for both sequencing/tracking and the voltage ripple limits. This application noteexplains these and other power-supply considerations that an engineer must think through whendesigning a power supply for an FPGA.

HDB3(High Density Bipolar三階高密度雙極性)碼是在AMI碼的基礎(chǔ)上改進(jìn)的一種雙極性歸零碼，它除具有AMI碼功率譜中無(wú)直流分量，可進(jìn)行差錯(cuò)自檢等優(yōu)點(diǎn)外，還克服了AMI碼當(dāng)信息中出現(xiàn)連“0”碼時(shí)定時(shí)提取困難的缺點(diǎn)，而且HDB3碼頻譜能量主要集中在基波頻率以下，占用頻帶較窄，是ITU-TG.703推薦的PCM基群、二次群和三次群的數(shù)字傳輸接口碼型,因此HDB3碼的編解碼就顯得極為重要了[1]。目前，HDB3碼主要由專用集成電路及相應(yīng)匹配的外圍中小規(guī)模集成芯片來(lái)實(shí)現(xiàn)，但集成程度不高，特別是位同步提取非常復(fù)雜，不易實(shí)現(xiàn)。隨著可編程器件的發(fā)展，這一難題得到了很好地解決。

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.

Introduction to Xilinx Packaging Electronic packages are interconnectable housings for semiconductor devices. The major functions of the electronic packages are to provide electrical interconnections between the IC and the board and to efficiently remove heat generated by the device. Feature sizes are constantly shrinking, resulting in increased number of transistors being packed into the device. Today's submicron technology is also enabling large-scale functional integration and system-on-a-chip solutions. In order to keep pace with these new advancements in silicon technologies, semiconductor packages have also evolved to provide improved device functionality and performance. Feature size at the device level is driving package feature sizes down to the design rules of the early transistors. To meet these demands, electronic packages must be flexible to address high pin counts, reduced pitch and form factor requirements. At the same time,packages must be reliable and cost effective.

Consumer display applications commonly use high-speed LVDS interfaces to transfer videodata. Spread-spectrum clocking can be used to address electromagnetic compatibility (EMC)issues within these consumer devices. This application note uses Spartan®-6 FPGAs togenerate spread-spectrum clocks using the DCM_CLKGEN primitive.

The SDI standards are the predominant standards for uncompressed digital videointerfaces in the broadcast studio and video production center. The first SDI standard,SD-SDI, allowed standard-definition digital video to be transported over the coaxial cableinfrastructure initially installed in studios to carry analog video. Next, HD-SDI wasto support high-definition video. Finally, dual link HD-SDI and 3G-SDIdoubled the bandwidth of HD-SDI to support 1080p (50 Hz and 60 Hz) and other videoformats requiring more bandwidth than HD-SDI provides.
