Spider Platform

The XUPSVH is designed with BittWare’s Spider platform, which is a low-profile PCIe platform optimized for thermal performance. The Spider platform combines a low-profile PCIe form-factor for high density, the ability to run larger loads, and a robust passive heatsink option designed for servers.

High-Speed Networking and I/O

The XUP-SVH is enabled for high-speed networking with up to two front panel QSFP Double Density (QSFP-DD) cages, each supporting two 40/100GbE or eight 10/25GbE channels. Serial expansion is available through an UltraPort SlimSAS connector (8x 24Gbps) that can be connected to a second PCIe interface, another XUPSVH, or other devices, including IBM’s POWER9 via OpenCAPI. A utility header provides a 1GbE interface, a PPS input, and a USB interface for debug and programming support.

Board Management Controller

The XUP-SVH 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 XUP-SVH with its BittWorks II software tools. The BittWorks II Toolkit is a suite of development tools that serves as the main interface between the BittWare board and the host system. The Toolkit includes drivers, libraries, utilities, and example projects for accessing, integrating, and developing applications for the BittWare board.

FPGA Example Projects

BittWare offers FPGA example projects to provide FPGA board support IP and integration for its UltraScale+ boards. The example projects easily integrate with the Xilinx Vivado tools and illustrate how to move data between the board’s different interfaces. All examples are available for download on BittWare’s developer website.
