CatiaMagic，原名MagicDraw，被达索收购后融入3DExperience产品协同研发管理平台中。该软件提供对SysML/UML/UAF语言的完整支持，提供独有的MagicGrid方法论，涵盖业务和任务分析、利益攸关者需要及需求分析、系统需求定义、系统架构定义、设计方案权衡、系统分析验证及协同设计管理等内容，支持早期对方案可行性进行快速验证，并更快地分析替代方案，探索更完整的设计空间。采用基于模型的协同设计，实现模型元素追溯，便于变更管理及影响分析、提高设计重用、沟通和理解质量。产品功能 • 专业的系统工程方法论基于INCOSE OOSEM方法和工程实践提出了适用于复杂产品开发的MagicGrid方法论。该方法按照产品不同的研制阶段需要关注的问题将设计过程分为问题域（产品需求分析）、解决方案域（产品方案设计）及实现域。在不同域内部，将分析过程细分为需求、行为、外部环境及能效指标四个视角维度，以便更全面的表达产品应具备的属性。通过不断的设计迭代，实现复杂产品的正向设计及完整的追溯过程。软件依据MagicGrid方法论，提供设计向导、流程模板，通过实践，帮助MBSE在研发各阶段落地实施。 • 仿真分析功能提供模型执行框架（OMG fUML、W3C SCXML、JSR223等）；支持模型调试和执行动画环境；支持用户交互界面建模和执行；内嵌求解器，支持与多学科专业分析工具

How to test Qt SCXML state machines

阅读更多关于 How to test Qt SCXML state machines

问题 I'm trying to verify the behavior of a state machine using Qt test framework. I simply don't get how I am supposed to tests Qt SCXML implementation. Sure there is QSignalSpy , but that is only for signals/slops which do not require the event loop to run. What I essentially want to do is: myStateMachine.submitEvent("MyEvent"); // Run event loop // Check result I tried to QCoreApplication::processEvents() this sometimes worked, but sometimes also got stuck when calling processEvents() . I guess

How to register C++ function to scxml ecmascript data model?

阅读更多关于 How to register C++ function to scxml ecmascript data model?

问题 This question is deprecated I have since converted my state machines to use an extra state to call the C++ function on enter and I trigger sendEvent when the function returns a value. Old question is as follows: I have a simple SCXML model designed in Qt. It is lacking some functionality such as listening to pub/sub queues, for which I want to register some functions into the QScxmlStateMachine instance so I can call them from the ECMAScript portion of the state machine. I took a look at the

SCXML parsing IOS

问题 Do anyone have any idea about writing SCXML parsers in IOS ? I went through this http://www.w3.org/TR/scxml/ and have idea about SCXML. I need to create parsing architecture now. Kindly let me know if anyone has idea. Thanks in advance. 回答1: SCXML is just XML, so if you simply want to parse the document, you only need an XML parser. This article has a good overview of various XML parsers available for iOS: http://www.raywenderlich.com/553/how-to-chose-the-best-xml-parser-for-your-iphone

What I essentially want to do is: myStateMachine.submitEvent("MyEvent"); // Run event loop // Check result I tried to QCoreApplication::processEvents() this sometimes worked, but sometimes also got stuck when calling processEvents() . I guess I might triggered an infinite loop. Also googling did not help, but there must be a way to do this
