The Xilinx UltraScale+ FPGAs are built on 16 nm process technology using 16FF+ FinFET 3D transistors to offer higher performance per watt than previous generations. Virtex UltraScale+ VU3P devices feature up to 40x 32.75 Gbit/s transceivers, which enable 400GbE, 100GbE, and 25GbE. The UltraScale+ FPGAs offer programmable system integration with over 115 Mb of on-chip memory, integrated 100G Ethernet MAC with RS-FEC and 150G Interlaken cores, and IP blocks for PCIe Gen3 x16 and Gen4 x8. Up to 2,280 DSP slices provide high-level DSP compute performance.
The XUPPL4 provides a variety of interfaces for high-speed serial I/O as well as debug support. Two QSFP28 cages are available on the front panel, each supporting 100GbE, 40GbE, four 25GbE, or four 10GbE channels, for a total of up to 200 Gbps of bandwidth. The QSFP channels are connected directly to the UltraScale+ FPGA via 8 transceivers. The QSFP cages can optionally be adapted for SFP+.
A Gen3 x16 or Gen4 x8 PCIe interface connects to the FPGA via 16 transceivers. A USB 2.0 interface provides BMC access. The board also supports precision timestamping with provision for a 1 PPS and reference clock input and output.
The XUPPL4 features up to 32 GBytes DDR4 on-board. Additional on-board memory includes Flash with factory default and support for multiple FPGA images.
The XUPPL4 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.
BittWare offers complete software support for the XUPPL4 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.
BittWare offers FPGA example projects to provide board support IP and integration for its Xilinx FPGA-based boards. The example projects easily integrate into existing FPGA development environments and illustrate how to move data between the board’s different interfaces. Available example projects include the following: PCIe Gen3x16 Base Project, PCIe DMA, DDR4, and SerDes (iBERT). All examples are available for download on BittWare’s developer website.
