Great products are composed of great individual components that are increasingly assessed from every possible physical perspective. But as you probably know, optimally designed components do not necessarily result in optimal systems. Eventually, the components are assembled, powered, sensed and controlled as an integrated system, and must therefore be simulated as a system to meet peak performance requirements and stringent safety standards. But building and testing integrated product systems and subsystems can be costly and may not identify optimal configurations and/or potential shortcomings. Systems simulation can help to overcome this challenge. Continue reading
For every product powered by batteries — cellphones, hybrid and electric vehicles, implantable medical devices, drones, industrial equipment — there is an end user who is concerned about a battery’s longevity. Whether you are trying to find an outlet to check your emails before your cellphone dies, wondering how many miles your drone can fly before it falls from the sky, or hoping to delay the surgical procedure needed to change the battery in your implanted defibrillator, battery longevity affects us all at one time or another.
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 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
As one of today’s avionics system engineers, you have a difficult task — integrating a diverse range of functionally complex components, provided by multiple suppliers, into a system that is reliable enough to ensure consistent aircraft performance and passenger safety. You also need to understand and meet numerous regulatory operating systems and protocols, including ARINC 653, ARINC 429, CAN and ARINC 664. 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 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. Continue reading
With the increase of unmanned aerial vehicles (UAVs, or drones) in the skies, the rapid rise of robotics, and the development of embedded technologies and autonomous smart systems for the Internet of Things, small teams of engineers face bigger and bigger challenges. While it was once enough to be an expert in a single type of physics, these complex, interacting systems require modern engineers to have more knowledge of multiphysics, model-based systems engineering and embedded software than their predecessors.
