HLS Code Generation Basics
R2026bYou can generate High-Level Synthesis (HLS) code from MATLAB code by using the HDL Coder™ app. The HDL Workflow Advisor generates HLS code and synthesize the generated code by using the synthesis tools.
Tools
| Workflow Advisor | Generate synthesizable HLS code and test benches from MATLAB code (Since R2022a) |
Functions
codegen | Generate HDL or High-Level Synthesis (HLS) code from MATLAB code |
coder.config | Create HDL Coder code generation configuration objects |
hdlsetuphlstoolpath | Set up system environment to access High-Level Synthesis (HLS) software (Since R2022a) |
convertToHlsConfig | Convert coder.HdlConfig object to
coder.HlsConfig object (Since R2026b) |
mlhdlc_demo_setup | Copy demo example files to the current or specified directory (Since R2026b) |
Objects
coder.HlsConfig | HLS code generation configuration object configuration object (Since R2026b) |
