Use Products and Blocks Supported for Code Generation

As you construct a model, to prevent issues later in the development process and potential rework, determine whether the code generator supports products and blocks that you want to use.

Blocks Supported for Code Generation

You can generate efficient code for a subset of Simulink built-in blocks and product-specific blockset blocks. The following tables list these blocks. In the tables, an information The letter "i" inside a blue rectangle. icon before the name of a block indicates that specific usage notes or limitations apply to code generation for that block. To view the usage notes and limitations, in the corresponding reference page, scroll down to the Extended Capabilities section at the bottom of the page and expand the C/C++ Code Generation section.

Simulink also provides a web page that summarizes characteristics of Simulink built-in blocks. The content, which is sourced from the Simulink block library, identifies blocks that are not recommended for production code generation and gives other usage guidelines. To view the page, in the MATLAB® Command Window, type showblockdatatypetable.

For detailed information about a block, see the block reference page.

For modeling guidelines regarding blocks, see Modeling Guidelines for Blocks.

Block Set Support for Code Generation

Several products that include blocks are available for you to consider for code generation. However, before using the blocks for one of these products, consult the documentation for that product to confirm which blocks support code generation.
