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 extended 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 revised version 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. In July 2019, Xilinx acquired NGCodec, developers of FPGA accelerated video encoders for video streaming, cloud gaming and cloud mixed reality services. NGCodec video encoders include support for H.264/AVC, H.265/HEVC, VP9 and AV1, with planned future support for H.266/VVC and AV2. In May 2020, Xilinx installed its first Adaptive Compute Cluster (XACC) at ETH Zurich in Switzerland. The XACCs provide infrastructure and funding to support research in adaptive compute acceleration for high performance computing (HPC). The clusters include high-end servers, Xilinx Alveo accelerator cards, and high speed networking. Three other XACCs will be installed at the University of California, Los Angeles (UCLA); the University of Illinois at Urbana Champaign (UIUC); and the National University of Singapore (NUS). Family lines of products Before 2010, Xilinx offered two main FPGA families: the high-performance Virtex series and the high-volume Spartan series, with a cheaper EasyPath option for ramping to volume production. The company also provides two CPLD lines: the CoolRunner and the 9500 series. Each model series has been released in multiple generations since its launch. With the introduction of its 28 nm FPGAs in June 2010, Xilinx replaced the high-volume Spartan family with the Kintex family and the low-cost Artix family. Xilinx's newer FPGA products use a High-K Metal Gate (HKMG) process, which reduces static power consumption while increasing logic capacity. In 28 nm devices, static power accounts for much and sometimes most of the total power dissipation. Virtex-6 and Spartan-6 FPGA families are said to consume 50 percent less power, and have up to twice the logic capacity compared to
