Developing Critical Applications for Multicore Environments: The SCADE Advantage

Multicore environments that feature clusters of microprocessors deliver a range of benefits, but they present a significant challenge to the engineers who design embedded software for automotive, aerospace and other mission-critical applications. ANSYS SCADE produces embedded software that enables the entire electronics architecture to perform reliably and all components to work together flawlessly, while accounting for the way essential tasks are distributed across multiple cores, how they communicate and how they are synchronized.

Eliminating the Language Barrier: A Single Tool for Avionics Systems Modeling with AADL, Aligned with the FACE (TM) Technical Standard - White Paper

Today, military organizations are beginning to encourage the adoption of the Architecture Analysis and Design Language (AADL) by their global suppliers. This system architecture language, which was originally developed in 2004 and is still evolving, is being embraced because of its ability to model both software and hardware components. By modeling systems via AADL, military organizations can understand the cost and performance implications of their avionics system designs at a very early stage, as they bring together components from multiple suppliers. In addition, since 2010, companies supplying avionics systems to military organizations have been challenged to adopt the Future Airborne Capability Environment (FACE) Technical Standard, a standard of The Open Group. The widespread adoption of the FACE™ approach has created an environment of software consistency and conformance, making it easy for defense organizations to partner with a wide variety of suppliers. In order to manage the increasing complexity of avionics systems design in this new age of dual compliance with the AADL specification and conformance to the FACE Technical Standard, software engineers need a modeling solution built to address both these industry standards.

综合全面的工具集SCADE System, 推动基于模型的系统工程顺利过渡到经过认证的嵌入式控制与显示软件

国际系统工程委员会(INCOSE)将系统工程定义为一种可实现成功系统的跨学科方法。该方法注重在研发周期尽早定义客户需求和所需功能,并记录需求,然后继续进行设计综合和系统验证。

系统工程的主要挑战在于提供明确、一致的规范,让所有参与方都可随时使用所有相关信息,建立所有活动之间的可跟踪性,并提供合适的验证和确认级别。行业中尚未广泛部署能够高效支持这些活动的工具。

软件工程由专业团队完成。基于模型的工具能为研发与验证活动提供很好的支持,尤其是在需要完成认证目标的情况下,例如航空业的DO-178B标准。

系统工程师一定要与软件研发团队互动,确保系统要求能有效转移到相关软件应用上。

正如INCOSE[1]发布的2020系统工程愿景报告中所述,基于模型的技术在系统工程中必须发挥关键作用。其中一个优势在于,MBSE会避免信息重复以及系统团队和软件团队之间的数据并行演进,由此减少信息再同步的噩梦。

Driving Speed and Reliability in Automotive Systems Engineering: The Need for a Model-Based Solution - White Paper

Few global industries are as focused on safety as automotive. As vehicles become smarter and more autonomous, engineers are challenged to maintain the integrity and security of hundreds of connected systems and components. The software that controls these electronics is absolutely mission-critical. A flaw in the control code can lead to relatively minor issues such as erroneous tire pressure readings or the loss of a GPS signal — but it can also result in high-risk events, such as braking failures or uncontrolled acceleration. As a manufacturer in the automotive industry, you cannot afford to be wrong.

To help ensure that all systems and components will operate reliably, automotive systems engineers require an advanced, automated tool for generating and verifying software code. In today’s fast-paced, high-stakes design environment, engineering teams can no longer rely on outdated tools and processes for ensuring system integrity. Instead, they require a comprehensive simulation solution offered by an industry leader focused on helping customers bring better products to market faster.

How Simulation-Based Digital Twins and the Industrial Internet of Things Can Improve Product and Process Performance - White Paper

Simulation has long been used to improve the design of nearly every physical product or process by providing the opportunity to evaluate a wide range of alternative designs prior to building physical prototypes. Simulation has also long been used to model different operating scenarios to develop control strategies that are incorporated into control algorithms to improve operations. The emergence of the Internet of Things (IoT) has created the potential for a transformational journey in which a simulation model of the product or process is tied through the Internet to sensors capturing data and to actuators controlling its operation. The result is a so-called digital twin of the physical product or process that can be used to analyze and diagnose its operation and optimize its performance and maintenance in real time. By using simulation in conjunction with the IoT, companies can analyze the performance of products in real-world operating conditions and make confident predictions about future performance to improve product operation and productivity, and to reduce the cost and risk of unplanned downtime.

Needed: A Model-Based Solution that is Aligned with the FACE Technical Avionics Software Standard - White Paper

The creation of a shared software development standard for avionics systems in 2010 has created new pressures for software engineers in this industry. The future airborne capability environment (FACE™) software technical standard supports the adoption of a common plat-form for avionics systems delivered to military organizations. It enables defense customers to benefit from a consistent set of technology standards, as well as partner with a wider variety of suppliers worldwide. The FACE standard increases productivity for avionics systems suppliers, as they no longer need to reinvent the wheel for each new customer order — instead, they can re-use many elements of their existing FACE-aligned software architectures. However, many avionics suppliers are struggling to understand and align to FACE requirements. What's’s needed is a new FACE-specific modeling solution that works in concert with proven avionics modeling packages that are already in use by industry leaders.
