A number of new and exciting workflow enhancements were included in ANSYS SCADE 17.2 for those who are validating and testing embedded software. In this blog, I’ll cover the top 3 enhancements.
Virtual System Testing Using Simplorer Entry
In ANSYS 17.2, all SCADE Suite users can immediately simulate and analyze virtual system prototypes thanks to the bundling of Simplorer Entry.
One of the main objectives of embedded software users is to perform closed-loop testing to tune the software application — as early as possible. As a best practice, embedding the application within a virtual environment is a great way to reduce testing costs. It can be performed first with simplified model of the environment using Modelica language then moved to high-fidelity models. Continue reading →
Developing an Internet of Things (IoT) enabled product is a complicated task, whether it’s an autonomous vehicle, a vehicle user interface like a car infotainment system, or a connected factory. IoT-enabled products contain hundreds, if not millions, of lines of embedded software code. And many of these products — and the systems and software that control them — are mission- or safety-critical. Therefore, developers must have confidence that the software code controlling these devices is 100% accurate and responds in the intended manner. Continue reading →
The Internet of Things and the abundance of smart applications have significantly increased the need for the safety critical embedded software that controls these devices. You’ve probably heard some of the following stats. Nearly 400,000 software and system engineers work in the oil and gas industry. In the energy and nuclear sectors, software-based instrumentation and controls have become state of the art. The aerospace industry has witnessed a 500 percent increase in source lines of code over the past decade. And, there are 10 million software lines of code in modern vehicles! Continue reading →
The tragic derailing of an Amtrak train near Philadelphia points out just one of the challenges facing the modern railroad industry — safety. The industry also must contend with rising energy costs, fast growth of capacity requirements in emerging markets, increasing certification costs and interoperability requirements. Continue reading →
The model-based systems engineering journey is evolutionary, not revolutionary. Deployment often starts with a single project or disciplinary area and becomes more sustainable as its business value is demonstrated. We’ve been studying MBSE deployments and the business value it delivers for some time now. Below I’ve shared some key success factors we’ve observed with deploying a sustainable MBSE initiatives, but first I’d like to share and event coming up that I think you may enjoy. Continue reading →
Today’s blog post is a continuation of a series on Systems Engineering for Smart Products. Remember the old Xerox commercial featuring a monk tasked with making 500 copies of a multi-page, handwritten document? Well, fast forward to 2014 and replace the monk with a systems engineer verifying hundreds of requirements against a textual-based description of a product, and you have a typical scene playing out across many engineering enterprises.

“A picture is worth a thousand words.” Pictures, or model-based designs, as engineers refer to them, provide a natural means of communication. With the newest release of ANSYS SCADE System 15.2, systems engineers can use models and interface control documents (ICDs), rather than text files and long lists of data, to create and manage their systems designs.
However, when precision and complexity come forth, “data dictionaries” enter the game. A dictionary is a way to manage information in an exhaustive way but without the model, it’s not easy to get an overview of your system. The issue you’re then faced with is the consistency between the model and the dictionaries — if inconsistent, the situation is worse than without the model. Continue reading →
Take five minutes and think about what you did today and you’ll see that embedded systems are everywhere. Let me show you what I mean.
You woke up, turned on your coffee machine, and got ready for work. Then maybe you took your car, the metro, the train or possibly the plane. Arrived at the office. Now you are using your computer, whose energy comes from maybe nuclear, solar or hydraulic resources. You are sitting on your chair in front of your desk, both transported to your country by ship. And if you look up through the window, for sure there is one satellite screening your area at the moment. Do you know that all these devices, from your coffee machine, to your car, the electrical plants and satellites, function thanks to the embedded code that defines their actions? Continue reading →
Today’s blog post is a continuation of a series on Systems Engineering for Smart Products.In my previous posting, I described how traditional systems engineering has evolved to model-based systems engineering (MBSE), in which the authoritative system definition no longer resides in a set of static text-based design documents, but rather in a dynamic model.
While the benefits of MBSE have been extensively documented, there has been little guidance on how to successfully deploy MBSE within an engineering enterprise. Through engagements with many A&D, automotive and energy companies, we have identified the following success factors. Continue reading →
In my last blog, I talked about the ability to control human–machine interfaces (HMIs) through mobile devices. The SCADE model-based embedded software suite features the automatic, one-click, generation of HMI executable applications from a single model over a variety of targets, including Android or iOS tablets and other similar devices. Here’s how it all comes together.
The code generated out of SCADE models is fundamentally independent from the target platform ― whether it is the hardware and associated drivers or the operating system ― as no system calls are being performed in this generated code. The portability of SCADE HMI models as executable applications is, thus, greatly facilitated, as the needs for adaptation then reside only in the main execution and interaction loops, or in the windowing system management. The always-wider adoption of international standards like OpenGL (for drawings) EGL (as the associated windowing system) also facilitates this task. Continue reading →
