Xilinx (赛灵思) 公司成立于1984年，总部设在圣何塞、都柏林和新加坡，1990年成为上市公司（NASDAQ：XLNX）。现场可编程门阵列（FPGA）发明者 ，代工生产模式的先锋 。

Xilinx (赛灵思)在技术、市场和经营业绩上均居半导体行业领导地位。 根据 iSuppli 公司市场分析师的介绍，Xilinx (赛灵思)在2010财政年度实现了18亿美元的收入，占有半导体行业可编程逻辑器件（PLD）部门50%以上的市场份额。

Xilinx(赛灵思)是全球领先的可编程逻辑完整解决方案的供应商。Xilinx研发、制造并销售范围广泛的高级集成电路、软件设计工具以及作为预定义系统级功能的IP（Intellectual Property）核。客户使用Xilinx及其合作伙伴的自动化软件工具和IP核对器件进行编程，从而完成特定的逻辑操作。

Xilinx公司成立于 1984年，Xilinx首创了现场可编程逻辑阵列（FPGA）这一创新性的技术，并于1985年首次推出商业化产品。眼下Xilinx满足了全世界对 FPGA产品一半以上的需求。Xilinx产品线还包括复杂可编程逻辑器件（CPLD）。在某些控制应用方面CPLD通常比FPGA速度快，但其提供的逻辑资源较少。Xilinx可编程逻辑解决方案缩短了电子设备制造商开发产品的时间并加快了产品面市的速度，从而减小了制造商的风险。与采用传统方法如固定逻辑门阵列相比，利用Xilinx可编程器件，客户可以更快地设计和验证他们的电路。而且，由于Xilinx器件是只需要进行编程的标准部件，客户不需要象采用固定逻辑芯片时那样等待样品或者付出巨额成本。Xilinx产品已经被广泛应用于从无线电话基站到DVD播放机的数字电子应用技术中。传统的半导体公司只有几百个客户，而Xilinx在全世界有7，500多家客户及50，000多个设计开端。其客户包括Alcatel，Cisco Systems，EMC，Ericsson，Fujitsu，Hewlett-Packard，IBM，Lucent Technologies，Motorola，NEC，Nokia，Nortel，Samsung，Siemens，Sony，Oracle以及Toshiba。

Xilinx, Inc. (/ˈzaɪlɪŋks/ ZY-lingks) is an American technology company, primarily a supplier of programmable logic devices. It is known for inventing the field-programmable gate array (FPGA) and as the first semiconductor company with a fabless manufacturing model.

Founded in Silicon Valley in 1984, Xilinx is headquartered in San Jose, USA, with additional offices in Longmont, USA; Dublin, Ireland; Singapore; Hyderabad, India; Beijing, China; Shanghai, China; Brisbane, Australia and Tokyo, Japan.

Major FPGA product families include Virtex (high-performance), Kintex (mid-range) and Artix (low-cost), and the retired Spartan (low-cost) series. Major computer software includes Xilinx ISE and Vivado Design Suite.

Xilinx designs, develops and markets programmable logic products, including integrated circuits (ICs), software design tools, predefined system functions delivered as intellectual property (IP) cores, design services, customer training, field engineering and technical support. Xilinx sells both FPGAs and CPLDs for electronic equipment manufacturers in end markets such as communications, industrial, consumer, automotive and data processing.

Xilinx's FPGAs have been used for the ALICE (A Large Ion Collider Experiment) at the CERN European laboratory on the French-Swiss border to map and disentangle the trajectories of thousands of subatomic particles. Xilinx has also engaged in a partnership with the United States Air Force Research Laboratory’s Space Vehicles Directorate to develop FPGAs to withstand the damaging effects of radiation in space, which are 1,000 times less sensitive to space radiation than the commercial equivalent, for deployment in new satellites.

The Virtex-II Pro, Virtex-4, Virtex-5, and Virtex-6 FPGA families, which include up to two embedded IBM PowerPC cores, are targeted to the needs of system-on-chip (SoC) designers.

Xilinx FPGAs can run a regular embedded OS (such as Linux or vxWorks) and can implement processor peripherals in programmable logic.

Xilinx's IP cores include IP for simple functions (BCD encoders, counters, etc.), for domain specific cores (digital signal processing, FFT and FIR cores) to complex systems (multi-gigabit networking cores, the MicroBlaze soft microprocessor and the compact Picoblaze microcontroller). Xilinx also creates custom cores for a fee.

The main design toolkit Xilinx provides engineers is the Vivado Design Suite, an integrated design environment (IDE) with a system-to-IC level tools built on a shared scalable data model and a common debug environment. Vivado includes electronic system level (ESL) design tools for synthesizing and verifying C-based algorithmic IP; standards based packaging of both algorithmic and RTL IP for reuse; standards based IP stitching and systems integration of all types of system building blocks; and the verification of blocks and systems. A free version WebPACK Edition of Vivado provides designers with a limited version of the design environment.

Xilinx's Embedded Developer's Kit (EDK) supports the embedded PowerPC 405 and 440 cores (in Virtex-II Pro and some Virtex-4 and -5 chips) and the Microblaze core. Xilinx's System Generator for DSP implements DSP designs on Xilinx FPGAs. A freeware version of its EDA software called ISE WebPACK is used with some of its non-high-performance chips. Xilinx is the only (as of 2007) FPGA vendor to distribute a native Linux freeware synthesis toolchain.

Xilinx announced the architecture for a new ARM Cortex-A9-based platform for embedded systems designers, that combines the software programmability of an embedded processor with the hardware flexibility of an FPGA. The new architecture abstracts much of the hardware burden away from the embedded software developers' point of view, giving them an unprecedented level of control in the development process. With this platform, software developers can leverage their existing system code based on ARM technology and utilize vast off-the-shelf open-source and commercially available software component libraries. Because the system boots an OS at reset, software development can get under way quickly within familiar development and debug environments using tools such as ARM's RealView development suite and related third-party tools, Eclipse-based IDEs, GNU, the Xilinx Software Development Kit and others. In early 2011, Xilinx began shipping a new device family based on this architecture. The Zynq-7000 SoC platform immerses ARM multi-cores, programmable logic fabric, DSP data paths, memories and I/O functions in a dense and configurable mesh of interconnect. The platform targets embedded designers working on market applications that require multi-functionality and real-time responsiveness, such as automotive driver assistance, intelligent video surveillance, industrial automation, aerospace and defense, and next-generation wireless.

Following the introduction of its 28 nm 7-series FPGAs, Xilinx revealed that several of the highest-density parts in those FPGA product lines will be constructed using multiple dies in one package, employing technology developed for 3D construction and stacked-die assemblies. The company’s stacked silicon interconnect (SSI) technology stacks several (three or four) active FPGA dies side-by-side on a silicon interposer – a single piece of silicon that carries passive interconnect. The individual FPGA dies are conventional, and are flip-chip mounted by microbumps on to the interposer. The interposer provides direct interconnect between the FPGA dies, with no need for transceiver technologies such as high-speed SERDES. In October 2011, Xilinx shipped the first FPGA to use the new technology, the Virtex-7 2000T FPGA, which includes 6.8 billion transistors and 20 million ASIC gates. The following spring, Xilinx used the 3D technology to ship the Virtex-7 HT, the industry’s first heterogeneous FPGAs, which combine high bandwidth FPGAs with up to sixteen 28 Gbit/s and seventy-two 13.1 Gbit/s transceivers to reduce power and size requirements for key Nx100G and 400G line card applications and functions.

In January 2011, Xilinx acquired design tool firm AutoESL Design Technologies and added System C high-level design for its 6- and 7-series FPGA families. The addition of AutoESL tools extends the design community for FPGAs to designers more accustomed to designing at a higher level of abstraction using C, C++ and System C.

In April 2012, Xilinx introduced a redesign of its toolset for programmable systems, called Vivado Design Suite. This IP and system-centric design software supports newer high capacity devices, and speeds the design of programmable logic and I/O. Vivado provides faster integration and implementation for programmable systems into devices with 3D stacked silicon interconnect technology, ARM processing systems, analog mixed signal (AMS), and many semiconductor intellectual property (IP) cores.
