Model Advisor Checks for High-Integrity Modeling Guidelines

The Simulink® Check™ Model Advisor provides High-Integrity System Modelling checks that you can use to verify compliance with safety standards, including:

The high-integrity guidelines and their corresponding checks are summarized in the table. For the guidelines that do not have Model Advisor checks, it is not possible to automate checking of the guideline. Guidelines without a corresponding check are noted as not applicable.

To check compliance with High Integrity System Model standards, run the high-integrity checks from these Model Advisor folders:

  • By Task > Modeling Standards for DO-178C/DO-331 > High-Integrity Systems

  • By Task > Modeling Standards for IEC 61508 > High-Integrity Systems

  • By Task > Modeling Standards for IEC 62304 > High-Integrity Systems

  • By Task > Modeling Standards for EN 50128/EN 50657 > High-Integrity Systems

  • By Task > Modeling Standards for ISO 26262 > High-Integrity Systems

  • By Task > Modeling Standards for ISO 25119 > High-Integrity Systems
