SimDiff

SimDiff is the industry-standard Simulink diff tool. SimDiff compares two Simulink model files for additions, deletions, and changes to blocks, lines, configuration parameters, model properties, subsystems, and annotations.

In other words, it computes differences that affect the logic of the model, not just simple layout changes. In addition to the fastest, most accurate Simulink model diff, SimDiff Pro also includes reporting and auditing to support safety-critical model-based development.
