Overview

BittWare’s XUSP3S is a 3/4-length PCIe x8 card based on the Xilinx Virtex or Kintex UltraScale FPGA. The high-performance UltraScale devices provide increased system integration, reduced latency, and high bandwidth for systems demanding massive data flow and packet processing. The board offers flexible memory configurations supporting up to 64 GBytes of memory, sophisticated clocking and timing options, and four front panel QSFP cages, each supporting up to 100 Gbps (4×25) – including 100GbE. The XUSP3S also incorporates a Board Management Controller (BMC) for advanced system monitoring, which greatly simplifies platform integration and management. All of these features combine to make the XUSP3S ideal for a wide range of data center applications, including network processing and security, acceleration, storage, broadcast, and SigInt.

Xilinx Virtex or Kintex UltraScale FPGA

The Xilinx UltraScale FPGAs are built on 20 nm process technology and provide ASIC-like clocking for scalability, performance, and lower dynamic power. UltraScale devices are available in two variants: Virtex and Kintex; the XUSP3S board supports both. The Virtex devices feature two types of multi-gigabit transceivers: 32x 16Gb/s (GTH) and 16x 32.75 Gb/s (GTY), while Kintex devices have 48x GTH. The GTY transceivers enable 400GbE, 100GbE, and 25GbE. The Kintex FPGAs support 5,520 DSP slices, while the Virtex supports 768. The UltraScale FPGAs provide four integrated blocks for PCI Express, supporting x8 Gen3 Endpoint and Root Port designs. Integrated blocks for 150 Gb/s Interlaken and 100 Gb/s Ethernet (100G MAC/PCS) enable simple, reliable support for Nx100G switch and bridge applications.

I/O Interfaces

The XUSP3S provides a variety of interfaces for high-speed serial I/O as well as debug support. Four QSFP28 cages are available on the front panel, each supporting 100GbE, 40GbE, four 25GbE, or four 10GbE channels, for a total of up to 400 Gbps of bandwidth. The four QSFPs can also be combined for 400GbE. The QSFP channels are connected directly to the UltraScale FPGA via 32 Gb/s GTY transceivers (or GTH for Kintex devices). The QSFP cages can optionally be adapted for SFP+.

Two Gen3 x8 PCIe interfaces connect to the FPGA via 16 GTH transceivers, allowing for a x8 PCIe connection in a standard slot or two x8 interfaces in a bifurcated slot. An optional serial expansion interface on the back side of the board provides a 16x GTH transceiver port connection to the FPGA and can be used to add serial memory, such as Hybrid Memory Cube (HMC). The expansion site can also be used to connect an additional two x8 PCIe interfaces to the FPGA via a cable assembly connecting to an adjacent board that supports PCIe bifurcation, allowing for a total of four x8 PCIe interfaces.

A USB 2.0 interface is available for debug and programming support. The board also supports timestamping with provision for a 1 PPS and reference clock input.

Memory

The XUSP3S features up to 32 GBytes DDR4 on-board as well as two SODIMM sites that support standard DDR4 and proprietary QDR-II+ SODIMMs. Memory card options include up to 16 GBytes of DDR4 with optional ECC or up to 72 MBytes QDR-II+ (2 banks x18). Additional on-board memory includes Flash with factory default and support for multiple FPGA images.

Board Management Controller

The XUSP3S features an advanced system monitoring subsystem, similar to those typically found on today’s server platforms. At the heart of the board’s monitoring system lies a Board Management Controller (BMC), which accepts Intelligent Platform Management Interface (IPMI) messaging protocol commands. The BMC provides a wealth of features, including control of power and resets, monitoring of board sensors, FPGA boot loader, voltage overrides, configuration of programmable clocks, access to I2C bus components, field upgrades, and IPMI messaging. Access to the BMC is via PCIe or USB. BittWare’s BittWorks II Toolkit also provides utilities and libraries for communicating with the BMC components at a higher, more abstract level, allowing developers to remotely monitor the health of the board.

BwMonitor in the BittWorks II Toolkit provides a view into the board management capabilities of your BittWare hardware.

Development Tools

BittWorks II Toolkit

BittWare offers complete software support for the XUSP3S with its BittWorks II software tools. Designed to make developing and debugging applications for BittWare’s boards easy and efficient, the Toolkit is a collection of libraries and applications that provides the glue between the host application and the hardware. A variety of features allow developers to take full advantage of the Xilinx UltraScale FPGA capabilities on the BittWare board, including FPGA control via PCIe, Flash programming, custom ISR scripts, and convenient control of FPGA loads. The Toolkit supports 64-bit Windows and Linux platforms and can connect to the board via PCIe or USB, providing a common API no matter the connection method.

FPGA Development Kit

BittWare’s FPGA Development Kit (FDK) provides FPGA board support IP and integration for BittWare’s FPGA-based boards. The FDK includes FPGA components that provide preconfigured physical interfaces, infrastructure, and examples, drastically cutting development time and easily integrating into existing FPGA development environments.

Working example projects are available for each board which illustrate how to move data between the board’s different interfaces. Supported interfaces include DDR4, QDR-II+, PCIe, 10GbE, LVDS, SerDes, and Double Data Rate I/O.
