Coding Standards and Code Metrics

MISRA, AUTOSAR, CERT, and JSF coding rule sets, custom coding rules, code metrics

To specify which coding standards you want to check, for instance, MISRA C™:2012 or AUTOSAR C++14, use the coding standard options. To see code complexity metrics in your analysis results, for instance, cyclomatic complexity and number of calling or called functions, use the code metrics option.

Check for and Review Coding Standard Violations
Check for violations of AUTOSAR C++14, CERT^® C, CERT C++, CWE, MISRA C, MISRA™ C++, JSF AV C++, or ISO-17961 standards with Polyspace Bug Finder.
Enforce Naming Conventions for C/C++ Variables and Functions
Enforce naming conventions and other style guidelines on C/C++ code with Polyspace.
Reduce Software Complexity by Using Polyspace Checkers
Enable and configure the software complexity checkers to identify issues that make your code difficult to read, understand, and debug.

MISRA or JSF Rules

Avoid Violations of MISRA C Rules 8.x
Avoid conflicting declarations or unintended modification of variables.
Coding Rule Subsets Checked Early in Analysis
Adjust your coding rules checking for a faster analysis.

Code Complexity Metrics

Compute Code Complexity Metrics Using Polyspace
Enforce limits on code complexity metrics such as cyclomatic complexity and depth of nesting.
HIS Code Complexity Metrics
See which code complexity metrics supported in Polyspace are part of the Hersteller Initiative Software (HIS) standard.

User Defined Coding Standards

Find Polyspace Bug Finder Checkers That Map to Coding Rules in User-Defined Coding Standard
Find Bug Finder checkers that can check for the coding rules in your user-defined coding rule standard.
Create User-Defined Coding Standard by Using Polyspace Bug Finder Checkers
Map Bug Finder checkers to coding rules in a user-defined coding standard in a sharable .pschk file.

Modify Checker Behavior

Modify Default Behavior of Bug Finder Checkers
