Model Using System Objects
R2026bA System object is a specialized MATLAB® object that you can use to implement or simulate dynamic systems with inputs that change over time.
With HDL Coder™, you can use predefined or user-defined System objects during code generation in MATLAB. System objects have these advantages:
Reuse of Components: Save time during design and testing by using existing System object components.
Customization: Design and qualify custom System objects for reuse in multiple designs.
Algorithm Definition: Define your algorithm in a System object once, and reuse multiple instances of it in a single MATLAB design.
Modularity and Readability: HDL code that you generate from System objects is modular and readable.
You can use the predefined System objects available with MATLAB, DSP System Toolbox™, and Communications Toolbox™ to generate HDL code. For more information, see Predefined System Objects Supported for HDL Code Generation.

Model States and Delays in HDL Code by Using Persistent Variables and System Objects
Model state and delays in a MATLAB® design for HDL code generation by using persistent variables and System objects™. In this example, you use two versions of the same Sobel edge-detection algorithm to compare both approaches and examine the resulting hardware resources in the code generation report.
