Abstract: As the degree of automation continues to increase, the intelligent SoC content in automobiles is growing faster than the general semiconductor market. As a result, the traditional automotive electronics suppliers are being rapidly joined in the market by many other established semiconductor companies and startups, as well as OEMs seeking differentiation through increased vertical integration. This ever-growing set of players all need to meet the functional safety requirements specified in standards such as ISO 26262. A process called Failure Modes, Effects, and Diagnostic Analysis (FMEDA) is critical to meeting these requirements. FMEDA so far has largely been the preserve of consultants using spreadsheet-based approaches. But now, automotive semiconductor design projects are looking for tools offering greater automation and consistency, as well as greater ownership and integration with the design and verification flow, of the FMEDA process. We believe the inherent ambiguity of functional safety standards will finally converge into a consolidated EDA standard to enable automation, results consistency, and information exchange between integrators into a product development lifecycle, analogous to industry standards for hardware description languages, timing, and power constraints.
In this workshop, Cadence will present the Midas™ Safety Platform, and how it uses the Unified Safety Formal (USF) – a formalized method for safety analysis and specification of safety mechanisms proposed as a candidate standard to Accellera’s Functional Safety Working Group – to provide a holistic and automated approach to FMEDA at the architectural, design, and diagnostic coverage verification stages. We will demonstrate how USF provides the links between the FMEDA process and digital design and verification flows for both digital and analog/mixed signal, to provide a complete and consistent approach to meeting functional safety requirements.
