Xilinx Vitis Core Development Kit / PetaLinux 2020.2 Windows / Linux

The Vitis unified software platform includes:

  • Comprehensive core development kit to seamlessly build accelerated applications
  • Rich set of hardware-accelerated open-source libraries optimized for Xilinx FPGA and Versal ACAP hardware platforms
  • Plug-in domain-specific development environments enabling development directly in familiar, higher-level frameworks
  • A Growing ecosystem of hardware-accelerated partner libraries and pre-built applications

Xilinx Vitis Core Development Kit 2020.2

Complete set of graphical and command-line developer tools that include the Vitis compilers, analyzers and debuggers to build, analyze performance bottlenecks and debug accelerated algorithms, developed in C, C++ or OpenCL. Leverage these features within your own IDEs or use the standalone Vitis IDE.

What is new 

ADF: Adaptive Data Flow

  • Compiler:
    • Event tracing on PLIO or GMIO
    • Event tracing also on Hardware
    • Heat Map generation: %utilization of all AI Engines
    • Supports different PL frequencies for PL kernels and PLIOs
  • Vitis IDE for AI Engines
    • Pipeline view
    • Vector register view
    • Internal memory views East, West North, South
    • External memory

Vitis HLS

  • Vitis HLS replaces Vivado HLS in Vivado (it was already default for Vitis and C based kernel compilation in 2020.1)
    • Adds array reshape and partitioning pragmas for top function ports
  • The tool is now installed in its own directory ./Vitis_HLS/2020.2 alongside Vitis and Vivado
  • HLS design migration information has been updated in UG1391
  • Vitis HLS user guide is UG1399, the full content is also available in HTML
  • Updated design examples on GitHub, they can also be loaded automatically from the Vitis HLS GUI (from the “Git Repositories” sub-window) for direct access
  • Support for SIMD programming
  • Support for on-chip block RAM ECC flags via the bind_storage pragma (Vivado flow only) to monitor error correction logic generated by the RAM blocks
  • GUI has a simplified toolbar icon layout, new reporting sections for interfaces and AXI4 including bursts
  • Non-default options can be filtered for quick review in “Solution Settings”→”General” then “Show only non-defaults” tick mark
  • User can create and open a project in the GUI directly starting from Tcl using the -p option and passing the Tcl file as an argument: vitis_hls -p  <file>.tcl
  • Interactive FIFO depth sizing in GUI
  • Constrained random testing for AXI interfaces now visible in the GUI

Versal Only Features

  • Vitis HLS now infers the dedicated single clock cycle accumulation for floating point (adder or multiplier) of the DSP58 block to implement efficient high throughput accumulation
  • Timing libraries updated for Versal production target devices

Vitis compiler & linker (v++)

  • Improved RTL-Kernel Integration:  Enhancements for packaging & integrating RTL IPs as kernels within Vitis applications, including support for user-managed RTL kernels (not controlled by XRT APIs) and improvements to IP Packager within Vivado to support this flow.
  • Multiple Implementation Strategies for Timing Closure: Vitis compiler & linker (v++) now supports launching & running multiple Vivado implementation strategies at the same time during hardware builds. This enables users to explore & assess all results and select the best strategy for final FPGA binary (xclbin) creation.

Versal Only Features

  • In 2020.2, as long as the hardware design stays the same, aiecompiler will only recompile and update to the software when AIE program is modified. The v++ linking stage is not re-run and it goes directly to the package step. This allows users to easily and quickly iterate on the AIE program after the HW has been fixed.
  • System Level template will be provided which includes AIE, PL and PS design files.
  • AIE tools features integrated into Vitis IDE, such as displaying pipeline information, storage view, parallel compilation etc.

Vitis IDE

  • Version Control for Vitis Projects: Integration with Git version control for Vitis Projects enables collaboration across multiple developers and teams.
  • Improvements to Project Hierarchy: Acceleration kernel and host applications are now separate projects under top-level System Project enabling a user to compile the host application and hardware kernels separately.
  • Improvements to Board Support Package (BSP) Build times: For platform projects with standalone domains, the Board Support Package (BSP) drivers compiles in parallel to speed up application build time.
  • Ease-of-Use for Host Application Debug: Processing System registers can be now be exported as a file from the Vitis GUI for debug.
  • Profiling System Projects: Top-level System Projects now offers more control over specifying profiling features via the Vitis GUI for the Vitis application acceleration flows.
