R2026b

Use naming conventions for model file names

Usage: High-Integrity System Modeling

Guideline ID: hisl_0031

Rules

hisl_0031: Model file names

For model file names:

  • Use these characters: a-z, A-Z, 0-9, and the underscore (_).

  • Use strings that are more than 2 and less than 64 characters. (Not including the dot and file extension).

Do not:

  • Start the name with a number.

  • Use underscores at the beginning or end of a string.

  • Use more than one consecutive underscore.

  • Use underscores in file extensions.

  • Use reserved identifiers.

Rationale

  • Readability

  • Compiler limitations

  • Model-to-generated code traceability

Verification

Check model file name (Simulink Check)

Example — Correct

  • My_model.slx

Example — Incorrect

Tips

  • The MATLAB limit for the number of characters you can use in model file names is 2048.
