Model Composer

Design, Simulate and Accelerate Path to Production

Model Composer is a Model-Based Design tool that enables rapid design exploration within the MathWorks Simulink® environment and accelerates the path to production on Xilinx programmable devices through automatic code generation. You can express and iterate through your algorithms using high-level performance-optimized blocks and validate functional correctness through system-level simulations. Model Composer transforms your algorithmic specifications to production-quality implementation through automatic optimizations that extends the Xilinx High Level Synthesis technology.


Key Feature and Benefits

Accelerate Design Iterations

  • High-Level of Abstraction: Algorithm-centric building blocks, with a focus on functionality, provide ease-of-use essential for domain experts to accelerate design exploration.
  • Support for Vectors and Matrices: Enables frame-based algorithm design that saves you the time and effort to move to an intermediate low-level model for implementation.
  • Application-Specific Libraries: Performance-optimized Computer Vision, Math, and Linear Algebra libraries available as blocks for simulation and high-performance implementation on Xilinx All-Programmable devices.
  • Import synthesizable C/C++ as Custom Blocks: Ability to create your own custom blocks for simulation and code generation provides greater flexibility to design your differentiated algorithms. 
  • Seamless Integration with Simulink: Direct connection with blocks from the Simulink product family enables system-level modeling and simulation and the ability to fully leverage the stimulus generation and data visualization capabilities of Simulink's graphical environment.
  • Integer, Floating and Fixed-point Support: Supports the native floating and integer data types in Simulink and the fixed-point and half data types supported by Vivado HLS.

Transform Algorithm to Architecture

  • Automatic optimizations: Analyses your algorithmic specification within Simulink and performs automatic optimizations to steer towards a micro-architecture that optimizes for throughput, reduces Block RAM utilization, and enables concurrent execution of blocks.
  • Accelerate IP Creation:  Transform your simulate-able designs into a RTL IP package that you can use within the Vivado IP Integrator and leverage all the benefits of its plug-and-play IP Integration design environment for complex designs.
  • Extend to System Generator for DSP: Leverage the benefits of Model Composer's ease-of-use and simulation speed, for portions of your design and export the synthesized RTL into your existing System Generator for DSP designs as new custom blocks.
  • Export to Vivado HLS: Advanced feature that provides a link between Simulink's graphical environment to design, simulate and validate your algorithms and Vivado HLS, by automatically generating everything you would need to further optimize your algorithm, including test vectors logged from simulation.
  • User Interface to Map RTL Interfaces:  Easy to use graphical interface to map the inputs and outputs in your design to supported RTL interfaces (AXI4-Lite, AXI4-Stream, AXI4-Stream Video, FIFO, Block RAM) and video formats (AXI4-Stream Video) for implementation.
  • Automatic Test Bench Generation: Automatic logging of test vectors from simulation and generation of test bench to verify functional equivalence between the executable design and generated code.
