Xilinx Alveo U280 with Virtex Ultrascale+ FPGA

Bittware 520N with Stratix 10 FPGA

This contains the compiler with high-level-synthesis features, report generation, and an emulator for testing. New optimizaiton features depend mostly on this tool.

This translates and maps your design to a bitstream, roughly the FPGA counterpart to an assembler in the CPU world. Since the FPGA backend has millions of registers, lookup tables and wires to chose from, this process takes a long time.

Xilinx Vivado, version selected and automatically loaded along with Vitis (above).

Intel Quartus, version selected and automatically loaded along with the BSP (below).

Intel Quartus, version selected and automatically loaded along with the BSP (below).

This component is configured on the FPGA and provides base funtionality like PCIe, and DDR or HBM2 controllers.

Xilinx shell

ml xilinx/u280

Part of Bittware Board Support Package (BSP), available with (_max) and without (_hpc) external channels for direct FPGA-to-FPGA communication.

ml bittware/520n (module combines FPGA shell and driver)

This is a software component that controls the interaction with the FPGA shell.

Xilinx XRT

ml xilinx/xrt

Part of Bittware Board Support Package (BSP), available with (_max) and without (_hpc) external channels for direct FPGA-to-FPGA communication.

ml bittware/520n (module combines FPGA shell and driver)

A specific coupling of XRT and Vitis versions is recommended and automatically resolved by the modules (version strings don’t match). Multiple pairs of XRT+Vitis can use the same shell. Detail page. Xilinx Vitis, XRT and U280 shell versions

Development tools need a sufficiently recent BSP version to work with. Detail page. Intel OpenCL SDK to BSP Mapping

When you submit a job into the fpga partition for hardware execution, with this contraint you request a fitting FPGA platform, shell and driver. You still need to load the corresponding modules. For synthesis and emulation, no constraint is needed, but you need to use the same modules as for later hardware execution.
