hisl_0307: Configuration Parameters > Diagnostics > Connectivity > Buses

R2026b

Set connectivity bus diagnostics to error to improve design robustness

Usage: High-Integrity System Modeling

Guideline ID: hisl_0307

Rules

hisl_0307: Configuration Parameters > Diagnostics > Connectivity > Buses

In the Configuration Parameters dialog box, on the Diagnostics > Connectivity pane, set the Buses parameters as follows:

  • Unspecified bus object at root Outport block to error

  • Element name mismatch to error

  • Bus signal treated as vector to error

  • Non-bus signals treated as bus signals to error

Rationale

Improve robustness of design.

Verification

Check safety-related diagnostic settings for bus connectivity (Simulink Check)
