BittWare’s XUP-VV4 is an UltraScale+ VU13P FPGA-based PCIe card, ideal for high-density datacenter applications. The Xilinx UltraScale+ VU13P FPGA gives designers incredible performance potential, with 3.8M logic elements — yet with a power density that makes thermal management difficult. The XUP-VV4 meets this challenge with BittWare’s Viper platform, supporting large FPGA loads, up to 512 GBytes DDR4, and 4x 100 Gbps Ethernet.
BittWare’s Viper platform uses advanced computer flow simulation to drive the physical board design in a thermals first approach, including the use of heat pipes, airflow channels, and arranging components to maximize the limited available airflow in a server. The XUP-VV4 features air cooling by default, but liquid cooling is also available. The board features the D2104 lidless package from Xilinx—allowing the heat pipes to contact the die directly, instead of through the heat spreader lid.
