Safety Analysis

Perform systematic safety analysis by leveraging design and simulation artifacts

You can use the Safety Analysis Manager to perform safety analysis, such as Failure Mode and Effects Analyses (FMEAs) and Functional Hazard Assessments (FHAs). Automate analysis and export your results.
