Functional Safety

Functional Safety

The core mission of every safety-critical standard is to ensure the absence of unreasonable risk due to malfunctioning systems resulting in damage to persons or property. These standards guide programs through risk analysis and Safety Integrity Level (SIL) determination, hardware and software development procedures, and the supporting confirmation measures required to pass certification. Adhering to these standards adds a layer of complexity on to already complex development workflows, often resulting in unplanned time and resource overhead. It is critical that programs take a holistic approach when evaluating the solutions and tool chain deployed into a safety-critical project. Mentor design and verification solutions combined with Siemens Lifecycle Management tools constitute a portfolio of integrated products covering every step of your safety-critical workflow. Below please find the new DO-254 course, on demand seminars covering IEC 61508, panel discussions with users and many articles on key technologies to get you started.

Introduction to DO-254

Introduction to DO-254 Course | Subject Matter Expert - Byron Brinson | Functional Safety Topic

DO-254 has been around for over 15 years and has been applied almost exclusively in the commercial Aerospace industry. Because it has been focused in a subset of the electronic hardware market, many engineers and companies have little to no knowledge of DO-254.

However, in recent years, the airplane manufacturers have sought to create or update aircraft with newer technology to make them more functional, efficient and safer. As a consequence of this initiative there are two challenges have come to the surface...

Application SW Development Demo

With the growth of SW, studies indicate a high end vehicle today is reaching 100MM lines of code and a Level 5 AV will have 400MM lines of code. With the push to develop SW functions that increase revenue and differentiation with no increase in COGS, the SW domain is critical. According to this McKenzie article, the value of SW in the vehicle is going to grow 11% per year reaching 30% of the cost of the Vehicle by 2030. Mentor has products that can help OEMs address the increasing challenge of designing and validating the application SW deployed in the vehicle.

 

The video demonstrates how one of Mentor’s SW tools, Vista™ Virtual Prototyping" in conjunction with Siemens TASS and Amesim supports OEM’s Application SW development.Vista provides SW developers a hosted run time environment eg. virtualized ECU. The demo shows SW running on the virtualized ECU very early in the process. As such developers can validate that the SW actually delivers the intended physical functions via Amesim as defined at the feature level in TASS. Again the concept is to shift validation earlier in the process by providing SW developers access to “virtualized” ECU’s.

As more and more ECU’s are built on expensive SOC architectures to meet the consolidation trend, it will be more difficult for SW developers to have access to HW for testing.
