Design Error Detection

Statically detect run-time errors and dead logic, derive design ranges

Design errors detection include dead logic, integer overflow, division by zero, and violations of design properties and assertions.万博1manbetx^®Design Verifier™uses formal methods to identify hard-to-find design errors in models without requiring extensive tests or simulation runs. You useSimulink Design Verifierto highlight blocks in a model containing design errors and blocks proven to be without them. For each block with an error, you calculate signal-range boundaries and generate a test vector that reproduces the error in simulation.

Detect Integer Overflow Errors

Detect integer overflow errors in a model by using design error detection analysis. Simulink® Design Verifier™ identifies the model constructs that may result in integer overflows and then either proves that the integer overflow cannot occur during simulation or generates test cases that demonstrates the integer overflow error.

Analyzing the Results for a Dead Logic Analysis

Demonstrates how to isolate potential causes of dead logic using thesldvexCommonCausesOfDeadLogicmodel. Dead logic detection finds unreachable objectives in the model that cause the model element to remain inactive.
