Model-Based Development (MBD) is a software engineering paradigm where the central focus is on the use of executable model that will allow automation of several tasks such as code generation, test cases generation (MTB) and verification. This paradigm is widely accepted in safety critical systems development and in particular the domain of avionics. MBD and MTB offer a cost efficient development of such systems and help establishing their conformity with avionics software standards DO-178C. Canada count several avionics software industry but very little work is carried in this area. Few tools exist but they are incomplete. There are few testing tools but they are not sufficient to cover all the aspects to be tested. This project tries to fill this gap and offer Model based approaches and techniques that helps model, and automatically test and verify avionics software. More specifically, this project addresses the creation of design models, and model-based testing and verification techniques for avionics software certification. The objectives are: (1) to specify, develop and verify software design models and more specifically create new UML profiles and Simulink design standards that suit avionics systems descriptions; (2) enable verification techniques and design by contract in the context of Model Driven Development; (3) develop low level requirements testing techniques in conformity with avionics software standards DO-178C and DO-331; and (4) enable low level requirements-based automatic test generation.

基于模型的开发 (MBD) 是一种软件工程范例，其核心重点是使用可执行模型，该模型将允许自动执行多项任务，例如代码生成、测试用例生成 (MTB) 和验证。这种范例在安全关键系统开发，特别是航空电子领域被广泛接受。 MBD 和 MTB 为此类系统提供了经济高效的开发，并帮助建立其与航空电子软件标准 DO-178C 的一致性。加拿大拥有多个航空电子软件行业，但在该领域开展的工作却很少。现有的工具很少，但它们并不完整。测试工具很少，但不足以覆盖所有要测试的方面。该项目试图填补这一空白，并提供基于模型的方法和技术，帮助建模、自动测试和验证航空电子软件。更具体地说，该项目致力于创建设计模型以及用于航空电子软件认证的基于模型的测试和验证技术。目标是： (1) 指定、开发和验证软件设计模型，更具体地说，创建适合航空电子系统描述的新 UML 配置文件和 Simulink 设计标准； (2) 在模型驱动开发的背景下启用验证技术和合同设计； (3) 开发符合航空电子软件标准 DO-178C 和 DO-331 的低水平要求测试技术； (4) 启用基于低级需求的自动测试生成。
