The following important information should be understood before beginning to use the Vivado Design Suite. Improved Productivity This entirely new tool solution was architected to increase the overall productivity for designing with the expanding portfolio of Xilinx devices. These new devices are now much larger and come with a variety of new technology including Stacked Silicon Interconnect Technology (SSIT), high speed I/O interfaces, hardened microprocessors and interfaces, analog mixed signal, etc. These new silicon features and capacity have allowed designers to move a lot more of the overall system design content into the FPGA. Designers are now faced with increased system design integration and verification challenges that require a different design methodology and toolset. This coupled with the increased capacity of the new devices made it clear a new tool solution was required. The Vivado Design Suite was developed to better address these new challenges. Product Overview The Vivado Design Suite is a completely new design solution created to address the design challenges described above. It is a complete replacement for the existing Xilinx ISE Design Suite of tools. It replaces all of the ISE point tools such as Xilinx Synthesis Tool (XST), implementation (ngdbuild-bitgen), Core Generator™system, Timing Constraints Editor, ISim, ChipScope™ analyzer, Xilinx Power Analyzer (XPA), FPGA Editor, PlanAhead™ design tool, SmartXplorer, etc. All of those capabilities are now built directly into the Vivado Integrated Design Environment (IDE) using a common data model and user interface. The Vivado Design Suite takes advantage of a common data model used to process the design from RTL elaboration all the way through bitstream generation. The entire design process can be executed in memory without having to write or translate any intermediate Release Notes Guide UG631 (v2012.2, v14.2) July 25, 2012 www.xilinx.com 4 Introducing Vivado Design Suite 2012.2 file formats. Having this common data model provides a lot of capabilities to analyze and affect the in-process design at each stage of the design flow. The entire design process can be managed push-button by using the Flow Navigator in the Vivado IDE or controlled manually by using Tcl. High-Level Synthesis Engineers can quickly simulate, analyze and modify the design without being distracted with implementation details. By starting with MATLAB®/Simulink® or untimed C/C++/System C, one can quickly explore different system architectures, evaluating them against key system criteria without investigating effort in writing RTL. The Vivado System Edition extends algorithm development above RTL with Vivado High-Level Synthesis (HLS) and System Generator for DSP. Vivado HLS (built on AutoESL tool technology) accelerates design implementation and verification by enabling C, C++, and SystemC specifications to be directly synthesized into VHDL or Verilog RTL, after exploring a multitude of micro-architectures based on design requirements. Functional simulation can be performed in C, providing an order of magnitude of acceleration over VHDL or Verilog simulation. This provides designers and system architects with a faster and more robust way of delivering quality designs. Choosing Vivado Design Suite or ISE Design Suite ISE Design Suite is an industry-proven solution for All Programmable Xilinx devices. The Xilinx ISE Design Suite continues to bring innovations to a broad base of developers, and extends the familiar design flow to all Xilinx FPGAs and Xilinx Zynq™-7000 projects. The next-generation Xilinx Vivado Design Suite is a revolutionary IP and system-centric design environment that accelerates developer productivity for dramatically faster integration and implementation with an easy to use IP-centric design flow and up to 4x improvement in run times. Vivado Design Suite 2012.2 supports the Xilinx 7 series FPGAs, which include the Virtex®-7, Kintex™-7 and Artix™-7 families. Vivado Design Suite offers better overall tool performance, especially on large designs. The design environment provides powerful flow customization and analysis using Tcl and Xilinx Design Constraints (XDC). Xilinx recommends customers starting a “new” design on Kintex K410 or larger device talk to your local FAE to determine if Vivado Design Suite is right for you. Xilinx does not recommend transitioning during the middle of a current design as design constraints and scripts are not compatible between the two tool flows. No Cost in 2012 for Current ISE Design Suite Warranted Seats If you purchased the ISE Design Suite in the last 12 months then you do not need to purchase the Vivado Design Suite during 2012. There is no additional cost for Vivado Release Notes Guide UG631 (v2012.2, v14.2) July 25, 2012 www.xilinx.com 5 Key New Features In Vivado Design Suite 2012.2 Design Suite during 2012.

XPS now includes a new configuration window which enables users to graphically configure each parameter with guaranteed routing, voltage and clock-correct automated selections. • 14.1 includes standard Zynq-7000 EPP configurations (for the ZC702 board), to enable developers to begin work immediately. • The new Zynq-7000 EPP MIO summary window provides an aligned, color-coded graphic view of peripheral pin outs for faster, easier and guaranteed-correct MIO selection. What’s New in SDK? • 14.1 now provides Xilinx SDK free of charge with all FlexLM license checks removed. SDK can be installed from a stand-alone installer (available on the Xilinx website) or within each ISE design tools edition installation. • Full support for Zynq-7000 EPP ° ° SDK now provides a full tools solution for bare-metal and Linux application development and profiling. Such tools include ARM GCC updated for bare-metal (EABI) and Linux development, Boot Image Creator, Flash programmer for QSPI, Device tree generator, and the remote system explorer (debug an IP-connected target board). SDK works with XPS to build and generate design-specific firmware including the first stage boot loader with provision for device security, fallback boot, and bitstream management. It will also combine, build and deploy a complete bootable system image to the Zynq-7000 EPP target platform.

Operating Systems and Available Memory The Microsoft Windows and Linux ® operating system (OS) architectures have limitations on the maximum memory available to a Xilinx program. Users targeting the largest devices and most complex designs may encounter this limitation. The ISE Design Suite has optimized memory and enabled support for applications to increase RAM memory available to Xilinx tools. Windows XP Professional 32-bit Xilinx applications are enabled to take advantage of the memory increase feature on Windows 32-bit systems. You must then modify Windows setting to get access to this larger memory. The standard Windows OS architecture limits the maximum memory available to a Xilinx process to 2 Gigabyte (GB). In Windows XP Professional, Microsoft created an option to support the ability of an application to address 3 GB of RAM. Xilinx ISE tools have built-in support for this option. To take advantage of this capability, you must also modify your Windows XP OS to enable this feature, which requires that you modify your boot.ini file by adding a “/3GB” entry to the end of the “startup” line. Before enabling 3 GB support for Xilinx applications, read the Microsoft Knowledge Base Article #328269 at http://support.microsoft.com/?kbid=328269. If you upgrade your computer to Windows XP Service Pack 1 (SP1) and you are using the /3GB switch, Windows may not restart without a patch from Microsoft. See the Xilinx Answer Record 17905 for more information at http://www.xilinx.com/support/answers/17905.htm. Additionally, before making this change, read: • Microsoft Bulletin Q17193 http://support.microsoft.com/default.aspx?scid=kb;en-us;Q171793, which contains information on “Application Use of 4GT RAM Tuning”. • Microsoft Bulletin Q289022 http://support.microsoft.com/default.aspx?scid=kb;en-us;q289022, which contains instructions for editing your boot.ini file. Linux For 32-bit Red Hat Enterprise Linux systems, the operating system can use the hugemem kernel to allocate 4 GB to each process. More information can be found on the Red Hat support site: http://www.redhat.com/docs/manuals/enterprise/ Release Notes Guide UG631 (v2012.2, v14.2) July 25, 2012 www.xilinx.com 33 System Requirements Cable Installation Requirements Platform Cable USB II and Parallel Cable IV are high-performance cables that enable Xilinx® design tools to program and configure target hardware. To install Platform Cable USB II, a system must have at least a USB 1.1 port. For maximum performance, Xilinx recommends using Platform Cable USB II with a USB 2.0 port. To install Parallel Cable IV, a system must have a parallel port connector and support parallel port communication. Cables are officially supported on the 32-bit and 64-bit versions of the following operating systems: Windows XP Professional, Windows-7, Red Hat Linux Enterprise, and SUSE Linux Enterprise 11. Additional platform specific notes are as follows: • Root privileges are required. • SUSE Linux Enterprise 11: The fxload software package is required to ensure correct Platform Cable USB II operation. The fxload package is not automatically installed on SUSE Linux Enterprise 11 distributions, and must be installed by the user or System Administrator. • Linux LibUSB support: Support for Platform Cable USB II based upon the LibUSB package is now available from the Xilinx website. See Xilinx Answer Record 29310 at: http://www.xilinx.com/support/answers/29310.htm.

Release Notes Guide UG631 (v2012.2, v14.2) July 25, 2012 www.xilinx.com 34 System Requirements Item Requirement Drive You must have a DVD-ROM for ISE Design Suite (if you have received a DVD, rather than downloading from the web). Ports To program devices, you must have an available parallel, or USB port appropriate for your Xilinx programming cable. Specifications for ports are listed in the documentation for your cable. Note: Installation of the cable driver software requires Windows XP Pro SP1 (or later), or Windows-7. If you are not using one of these operating systems, the cables may not work properly. Note: X Servers/ Remote Desktop Servers, such as Exceed, ReflectionX, and XWin32, are not supported. Network Time Synchronization When design files are located on a network machine, other than the machine with the installed software, the clock settings of both machines must be set the same. These times must be synchronized on a regular basis for continued proper functioning of the software.
