Synopsys: Synopsys DFTMAXTM LogicBIST Enables Automixed Signal Power-On Self-Test

Synopsys, the world's largest supplier of chip design automation EDA software and the world's largest chip interface IP provider, software quality and security solutions, announced that Renesas, the world's leading supplier of integrated circuit solutions, has mixed signals The Synopsys DFTMAXTM LogicBIST solution is deployed in large-scale integrated circuit (LSI) designs to meet automotive system integrators' requirements for automotive safety integrity. The DFTMAX LogicBIST solution allows automotive electronic systems to check for faults at power up or to identify conditions that could cause a fault and report their presence. In addition, this self-test feature achieves high fault coverage in a short run time to meet automotive electronics system level requirements. Renesas engineers can easily incorporate DFTMAX LogicBIST into their original design flow, while also adding Synopsys SpyGlass® DFT ADV technology to further improve fault coverage. With the assistance of Synopsys, according to ISO 26262 Automotive Functional Safety Standard Part 8, Renesas has certified DFTMAX LogicBIST for deployment in automotive designs.

In recent years, automakers have been advancing and accelerating the deployment of Electronic Advanced Driver Assistance Systems (ADAS) to assist drivers in driving and reducing accidents. But if these systems fail, they can lead to unacceptable consequences. Therefore, automakers and their suppliers of electronic systems have been working together to continuously improve the reliability and functional safety of integrated circuits (ICs). The Synopsys DFTMAX LogicBIST solution provides a security mechanism solution for detecting and marking faults that can cause failures to meet key requirements in the widely adopted ISO 26262 automotive functional safety standard. With DFTMAX LogicBIST and following optimal engineering practices, the risk of failure affecting automotive IC safety components can be minimized.

Akira Omichi, Senior Manager, Automotive Simulation Strategy Planning, Automotive Simulation Business Unit, Renesas Automotive Solutions, said: "Our mixed-signal automotive design requires the use of a minimum-scale chip-level power-on self-test solution and high faults for digital logic. Coverage to ensure functional security. The Synopsys DFTMAX LogicBIST solution meets these requirements even for designs with a relatively small number of digital logic, and DFTMAX LogicBIST is easy because it has reserved an easy-to-use hardware interface. Deployment. We plan to deploy it extensively in our mixed-signal LSI design."

Amit Sanghani, vice president of test automation at Synopsys Design, said: "We value the constructive collaboration with Renesas. DFTMAX LogicBIST was adopted by Renesas to validate the practicality and effectiveness of this solution in the design of automotive electronic systems. DFTMAX LogicBIST Designers can meet system design requirements by achieving high fault coverage in a short period of time. We are committed to helping engineers meet the specific testing requirements of automotive applications for electronic systems, making them fast to ISO 26262 standards."
