In today\u2019s post, Akshra Ramakrishnan<\/a> will talk about how to write<\/span> functional<\/span> requirements <\/span>for a driving scenario made in Driving Scenario <\/span>Designer, and<\/span> write test cases to verify and validate these requirements.<\/span><\/span>\u00a0Over to you, Akshra..<\/em><\/p>\n<\/div>\n

In a model-based design workflow, verification and validation<\/span><\/a> against a set of requirements is integral for successful system development and deployment. This ensures that your system design meets team-defined requirements, is compliant with team standards, and is free of run-time errors.<\/div>\n
Requirements Toolbox\u2122<\/span><\/a> lets you author, import, and validate requirements within MATLAB\u00ae and Simulink\u00ae, track their implementation and verification status, and trace them to the source blocks. You can use Simulink\u00ae Test\u2122<\/span><\/a> to author, manage, and execute tests for Simulink models. The Test Manager provides an interactive way to author tests from scratch, import existing test data and harness models, and organize your tests. You can also link requirements to test cases.<\/div>\n
In this blog, I will create and link requirements for a Driving Scenario Designer<\/span><\/a> scenario, and author test cases to verify those requirements.<\/div>\n

Scenario and Model Overview:<\/h2>\n
The scenario that I will be using and writing requirements for contains one ego vehicle, a right turn, one traffic light and one stop sign. The ego vehicle\u2019s path is pre-defined.<\/div>\n
