Detect Specified Minimum and Maximum Value Violations

Check ID: mathworks.sldv.minmax

Detect signals which exceed specified minimum and maximum values

Description

This analysis checks the specified minimum and maximum values (the design ranges) on intermediate signals throughout the model and on the output ports. If the analysis detects that a signal exceeds the design range, the results identify where in the model the errors occurred.

Following the recommendations of this check increases the likelihood of generating MISRA C:2012 compliant code for embedded applications, as well as code that complies with the CERT C and CWE standards.

Results and Recommended Actions

Result	Recommended Action
Failed, model incompatible	Resolve the model incompatibility.
