Scade One’s modern and engaging user interface (UI) offers numerous services, enabling you to quickly and efficiently design models and to focus on application development. To make the tool friendly to newcomers, interactive documentation and examples are included, ensuring a great starting experience.<\/p>\n
Upon launching Scade One, you will immediately notice its new and improved user interface, built from scratch on fresh, modern foundations. It is designed for today’s desktop environment, with multiples screens and 4k\/high-DPI screens. The UI is available in light and dark themes to suit your preferences.<\/p>\n

\n We want the tool to be easy to learn for new users. As you launch the application, you are greeted with a ‘Welcome page’ to get started quickly, which gives quick access to:<\/p>\n \n In addition to standard user documentation, Scade One features built-in user assistance accessible seamlessly from within the tool, without interrupting user workflow. You can invoke the help overlay at any moment, showing interactive documentation for the various parts of the user interface directly over the current view.<\/p>\n \n Creating graphical block diagrams can be a time-consuming process in model-based tools. This is why Scade One provides many features to make the design of readable block diagrams more efficient than ever:<\/p>\n \n \n \n Flexibility is a key area of focus for Scade One, allowing the manipulation of inconsistent or incorrect models, which typically occurs during model building or updates. For instance, the modeler allows blocks to overlap, accommodates textual blocks with syntax errors, and handles references to unknown declarations or operator instances that don’t match their definitions. Of course, your goal is to design a consistent and correct model, so the modeler features on-the-fly checks (see below) to detect inconsistencies and errors as you edit the model. Quick fixes are also available to correct errors or perform model-wide refactoring (e.g. rename a declaration and all its uses).<\/p>\n Such an increased flexibility eases model edition. In other model-based tools, you must declare an operator (or a constant, or an input) before using it. In Scade One, it is possible to do it the other way around:<\/p>\n \n \n This approach can be particularly useful during early design phases, where it feels natural to build your model in a top-down manner, starting from the root operator.<\/p>\n Scade One models are not just drawings. Diagrams and textual notation are based on a domain-specific programming language called Swan. This language is formally defined, from the syntax to static analyses, to guarantee model correctness \u2013 such as type consistency and the singular definition of flows.<\/p>\n In Scade One, these checks are seamlessly applied on-the-fly, as you edit the model, providing instantaneous feedback. There is no need to trigger explicit model checks: construction is natural and iterative, yielding a readable and correct model.<\/p>\n \n These analyses are used to offer additional services, such as auto-completion that considers identifier visibility or the ability to display inferred wire types as tooltips.<\/p>\n In this blog, we’ve demonstrated the new Scade One 2024 R1 visual coding experience. It offers many services to allow you to design models quickly and effectively, focusing on the development of your application rather than the intricacies of the tool.<\/p>\n In the next blog, we’ll discuss how Scade One bridges the gap between the ease of use of model-based tools and the expressiveness of programming.<\/p>\n Next in this series is Part 2<\/a>.<\/p>\n![](\"https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2023\/12\/scade-001-full-ui-light-1.png\")
