Ambarella's AI Vision Processor Meets Automotive Safety Goals with Mentor's Tessent Safety Ecosystem

June 25, 2020


AI vision silicon company achieves bring-up and meets ISO26262 safety goals using Tessent test technology.

Mentor, a Siemens business, announced that its Tessent software Safety ecosystem helped artificial intelligence (AI) vision silicon company Ambarella Inc. meet in-system test requirements and achieve ISO26262 automotive safety integrity level (ASIL) goals for its CV22FS and CV2FS automotive camera system-on-chips (SoCs).

The Tessent Safety ecosystem is a comprehensive portfolio of automotive IC test solutions with links to Mentor’s partners. The ecosystem delivers a range of IC test technologies, including in-line device monitoring, an approach that distributes embedded monitors throughout each semiconductor device, all connected through a common infrastructure to enable rapid detection and reporting of random failures anywhere in the system.

The design for Ambarella’s CV22FS and CV2FS SoCs utilized the following Tessent Safety ecosystem technologies:

  • Tessent LogicBIST software, which is a built-in self-test solution for testing the digital logic components of integrated circuits. It includes features targeted at nanometer SoC designs that reduce test costs and shorten time-to-market, while maximizing test quality.
  • Tessent MemoryBIST platform, which features a comprehensive automation flow that provides design rule checking, test planning, integration, and verification at either the RTL or gate level.
  • The Tessent MissionMode product, which provides a combination of automation and on-chip IP for enabling semiconductor chips throughout an automotive electronics system to be tested and diagnosed at any point during a vehicle’s functional operation.
