Xilinx Vitis Core Development Kit / PetaLinux 2020.2 (Windows / Linux)

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.
