Functional Safety

The demand for innovation continues to grow in safety critical markets such as automotive,
industrial and mil-aero. Companies must ensure their products operate correctly
and fail safely throughout the operational life.


Critical Challenges in Functional Safety

Innovation continues to drive higher levels of complexity across all safety-critical industries,
exacerbating the challenge to plan, execute, and close each safety activity. 

Requirements management and traceability

Requirements management is the backbone of a safety-critical lifecycle and standards demand requirements workflow, traceability, and verification be established.

Achieving a digital twin

Project teams must demonstrate functional behavior of large autonomous systems, a growing challenge when systems are exceeding millions of gates with hardware, software, digital and analog components.

Achieving zero defects

Tessent automotive-grade test products use the latest most advanced fault modeling to ensure that safety-critical products that target zero defects, are delivered with the highest quality possible.

Eliminating systematic failures

Safety-critical products must be bug free, a growing challenge as designs regularly exceed a million gates and include hardware, software and a mix of digital and analog signals.

Using Fault emulation for faster Time to Safety

Large full chip SoCs suffer performance degradation using fault simulation. Full software stack safety mechanisms consume billions of cycles leading to Time to Safety risks. Emulation can help to achieve faster Time to Safety.

Leveraging BIST for in-system test

In-System test technologies should be leveraged to provide a high level of failure detection for minimal additional silicon area in safety-critical designs.

Navigating the safety lifecycle

Project teams are challenged to understand, plan, execute and deliver on the required activities in a safety-critical lifecycle, resulting in significant schedule and cost impact. Services help bridge knowledge and resource gaps.

Performing tool assessment

Safety-critical projects must perform tool assessment and qualification, ensuring development tools aren’t introducing bugs/defects into the product.

Automotive safety and security

Automotive ICs can be secure w/o needing to be safe, but a safety critical IC cannot be safe w/o also being secure. Addressing safety and security in highly complex automotive SoCs is challenging even for veteran project teams.
