Guidelines to a successful ISO 26262 Lifecycle

New business models continue to drive disrupting innovation into the automotive market. This includes everything from mobility as a service, to the electrification of the drivetrain, to new autonomous fleet models for taxis, and the commercial movement of goods. Seeing this, many companies have made strategic decisions and investments to enter this arena. Both veteran silicon providers and newcomers to the automotive industry face a host of new challenges as their customers demand advanced functionality in the ISO 26262 compliant IC’s being developed.

To help shed light into some of these challenges, a team of safety experts across Siemens DISW and it’s partners have gotten together to detail some of the challenges we have seen in the industry and ways to mitigate or solve these challenges.

We certainly can’t address these challenges adequately in a single blog post. Therefore, we will be delivering a series of posts with each post discussing a challenge or best practice when developing a semiconductor intended to be compliant to ISO 26262. This series will provide safety managers, project leads, and practitioners a list of challenges that exist in various points in the ISO 26262 Safety lifecycle where considerable thought should be given and a plan formed prior to execution of the task or possibly even the development lifecycle.

To kick this off, it’s important to set the scope of this series.

ISO 26262 Functional Safety Series Scope

As hinted at in the introduction, this series mainly targets semiconductor companies developing ISO 26262 compliant ICs. This includes companies developing smaller mixed-signal ASICs to companies developing large multi-domain SoCs. However, the topics might be of interest to anyone focused on functional safety.

This series will discuss challenges that span across the entire safety lifecycle.
