Read any automotive-related article and I’m sure it discusses autonomous cars and Advanced Driver Assistance Systems (ADAS) – the benefits, the challenges and what the future may hold. More and more auto makers are moving towards autonomous developing vehicles, but many of the systems that will eventually be integrated into these vehicles to make them fully autonomous are being developed today. In fact, you probably have some of them in the car you are driving now — Collision Mitigation Braking, Lane Departure Warning, Blind Spot Warning, and Lane Keeping Assistance to name a few. These ADAS applications present a new set of challenges and require a multi-disciplinary development approach. You can read more about these development areas in a blog written by my colleague, Sandeep Sovani.
Today’s automotive systems are more complex, smarter and more autonomous than ever before, featuring functionality that no one could have imagined 10 years ago. Advanced sensors and electronics control everything from a vehicle’s speed and position to its entertainment and communications technologies. Radar, cameras and other sophisticated electronics are increasingly being incorporated into consumer vehicles.
In fact, today, more than 60 percent of a car’s cost comes from its advanced electronics and software systems. Since many of the functions guided by electronic systems are mission-critical, it’s essential that all automotive systems work together with complete reliability. The tens of millions of lines of software code that control these systems must be flawless. Continue reading
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 objective of simulation software is to inform design choices and provide validation results that include systems-level qualities, properties, characteristics, functions, behavior and performance insight. The simulation solution needs to go beyond the parts, or engineering disciplines of the design, and accurately describe the interacting effects of these parts as well as an accurate view into the detail of how these parts perform — essentially a virtual system.

This week our ANSYS webinars line-up includes topics such as model-based systems engineering, product-related tutorials with ANSYS Mechanical and ANSYS Polyflow, as well as a very interesting look at how fluid simulation is used to better everyday life.
Our Improving Your Everyday Life webinar is a part of the Convergence Webinar Series. ANSYS customers, University of Parma and Bissell Homecare, Inc, give us insights into how they use simulation. Later in the week, researchers at Intevac and Ozen Engineering show how they simulated the fluid—structure interactions (FSI) of the human left ventricle with Hybertrophic Obstructive Cardiomyopathy (HOCM) to better understand the condition in the hope of saving lives.

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
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
