2022.2 English

System Generator - the previous standalone design environment to develop DSP algorithms and generate HDL as an output - is now part of Vitis™ Model Composer. As a result of this product unification, HLS, AI Engine, and System Generator (HDL) libraries in the Xilinx toolbox have been merged to develop algorithms in a single MATLAB session.

The HDL Library in the Xilinx Toolbox contains all the library blocks previously contained in the System Generator blockset. Any existing System Generator design can be opened in Vitis Model Composer. Furthermore, you can develop new algorithms using the HDL library similarly to using the System Generator tool.

In addition, while Model Composer is a toolbox built onto the MathWorks Simulink environment, there are certain features of Simulink that are not supported in Model Composer. The following is a list of some of the unsupported features:

  • Simulink Performance Advisor.
  • Model referencing.
  • Variant subsystems.
  • Model Composer blocks do not support Simulink fixed-point types and only support Xilinx® fixed-point types.
  • Fixed-point designer does not integrate with Model Composer.
  • Accelerator mode and Rapid Accelerator mode.
