Synopsys, the world's leading provider of electronic design automation (EDA) software and chip interface intellectual property (IP), has announced that Renesas, a top global supplier of integrated circuit solutions, has implemented the Synopsys DFTMAX™ LogicBIST solution in its large-scale integrated circuit (LSI) designs. This implementation supports the growing demand for automotive safety integrity from system integrators in the automotive industry. The DFTMAX LogicBIST solution enables automotive electronic systems to detect faults at power-up or identify potential failure conditions and report them immediately. Its self-test feature ensures high fault coverage in minimal time, meeting the stringent requirements of automotive electronics at the system level. Renesas engineers can seamlessly integrate DFTMAX LogicBIST into their existing design flow, while also leveraging Synopsys SpyGlass® DFT ADV technology to further enhance fault detection capabilities. With Synopsys’ support, DFTMAX LogicBIST has been certified by Renesas according to ISO 26262, Part 8, making it suitable for use in automotive designs.
In recent years, automakers have been rapidly deploying Advanced Driver Assistance Systems (ADAS) to improve driver safety and reduce accidents. However, any failure in these systems could lead to serious consequences. As a result, automakers and their suppliers are continuously working together to enhance the reliability and functional safety of integrated circuits (ICs). The Synopsys DFTMAX LogicBIST solution offers a robust security mechanism to detect and flag faults that could lead to system failures, aligning with the key requirements of the widely adopted ISO 26262 automotive functional safety standard. By using DFTMAX LogicBIST alongside best engineering practices, the risk of failure in critical IC components can be significantly reduced.
Akira Omichi, Senior Manager of Automotive Simulation Strategy Planning at Renesas Automotive Solutions, stated, “Our mixed-signal automotive designs require a compact, chip-level power-on self-test solution that delivers high fault coverage for digital logic, ensuring functional safety. The Synopsys DFTMAX LogicBIST solution meets these needs, even for designs with limited digital logic. Its ease of deployment is due to the simple hardware interface it provides. We plan to implement this solution extensively across our mixed-signal LSI designs.â€
Amit Sanghani, Vice President of Test Automation at Synopsys, added, “We value our collaboration with Renesas and are pleased to see DFTMAX LogicBIST being used to validate its practicality and effectiveness in automotive electronic system designs. This solution allows designers to achieve high fault coverage quickly, meeting the system-level requirements. Our goal is to help engineers meet the specific testing needs of automotive applications, enabling them to comply with ISO 26262 standards efficiently.â€
