Model Composer enables the rapid simulation, exploration, and code generation of algorithms targeted for AI Engines from within the Simulink® environment. You can achieve this by importing AI Engine kernels and data-flow graphs into Model Composer as blocks and controlling the behavior of the kernels and graphs by configuring the block GUI parameters. Simulation results can be visualized by seamlessly connecting Simulink source and sink blocks with Model Composer AI Engine blocks.

Model Composer provides a set of AI Engine library blocks for use within the Simulink environment. These include:

  • Blocks to import kernels and graphs which can be targeted to the AI Engine portion of Versal™ devices.
  • Block to import HLS kernels which can be targeted to the PL portion of Versal devices.
  • Blocks that support connection between the AI Engine and the Xilinx HDL blockset.
  • Configurable AI Engine functions such as FIR, FFT, and IFFT.
Important: The AI Engine Lab can be done only in a Linux environment.
