R2026b

Configure fixed-step discrete solver for production code generation

Usage: High-Integrity System Modeling

Guideline ID: hisl_0041

Rules

For models used to develop high-integrity systems, in the Configuration Parameters dialog box, on the Solver pane, set parameters for solvers as follows:

hisl_0041: Configuration Parameters > Solver > Solver options
A

Type to Fixed-step.

Rationale

Generate code that is valid for production code generation.

Verification

Check safety-related solver settings for solver options (Simulink Check)

B

Solver to discrete (no continuous states).

Rationale

Generate code that is valid for production code generation.

Verification

Check safety-related solver settings for solver options (Simulink Check)

Tips

  • Generating code for production requires a fixed-step, discrete solver.
