Simplifying Requirements-Based Verification with Model-Based Design

With Model-Based Design, informal textual requirements can be modeled and simulated to verify behavior earlier, and then be automatically generated into code for an embedded target. The requirements can include temporal properties to define complex timing-dependent signal logic and can be incomplete or inconsistent. This can lead to errors and miscommunication in the design and test.

This talk shows you how you can model requirements and use the Logical and Temporal Assessments editor in Simulink Test™ to translate informal text requirements into unambiguous assessments with clear, defined semantics that can identify inconsistencies. The temporal assessment language, based on metric temporal logic, provides precise, formal semantics that is highly expressive and extensible to author readable assessments. You will learn how to enter assessments with conditions, events, signal values, delays, and responses using the interactive form-based editor. You can view the assessment in an English language-like statement that is easy to understand or view graphical representations that allow you to visualize the results and debug design errors.
