Synopsys Inc announced new functional safety derivatives of its popular DesignWare ARC processor IP to simplify and accelerate the development of automotive system on chips. The safety enhanced processor portfolio, which includes the Synopsys DesignWare ARC EM22FS, HS4xFS and EV7xFS processors, covers a broad range of automotive use cases from ultra low power control modules to artificial intelligence based vision processing. The Synopsys ARC FS cores integrate hardware safety features, such as redundant processors, error correcting code parity protection, safety monitors, and user-programmable windowed watchdog timers, to detect system errors. Comprehensive documentation related to safety, including enhanced-safety manuals, FMEDA and DFMEA reports accelerate SoC-level functional safety assessments. In addition, the Synopsys DesignWare ARC MetaWare Development Toolkit for Safety and MetaWare EV Development Toolkit for Safety help simplify the development of ISO 26262-compliant software.

The Synopsys DesignWare ARC EM22FS processor provides ultra low power, dual core lockstep functionality for ASIL D safety requirements in applications such as automotive sensors, braking and steering systems, and keyless entry. For use cases with ASIL B requirements the processor can be configured with the two cores operating independently. The Synopsys DesignWare ARC HS4xFS processors support single, dual and quad core implementations to enable high-performance safety applications, such as vehicle-to-vehicle, vehicle-to-infrastructure networking, and electric vehicle battery charging. In addition, the ARC EM22FS and HS4xFS processors can function as ASIL D compliant SoC-level safety managers with tight integration to Synopsys test solutions, including DesignWare STAR® Memory System, STAR Hierarchical System, STAR ECC, and TestMAX XLBIST, to provide a comprehensive functional safety test solution. The processors are supported by the Synopsys DesignWare ARC MetaWare Development Toolkit for Safety, a complete solution for developing, debugging and optimizing embedded software targeted for automotive applications. Included in the toolkit is an ASIL D certified compiler and collateral related to safety, including a safety manual and safety guide, to help developers of safety-critical systems fulfill the requirements of the ISO 26262 standard and prepare for compliance testing.

Mr John Koeter vice president of marketing for IP at Synopsys said that “The use of embedded processors in automobiles is growing rapidly, and achieving functional safety certification of these processor-based systems is essential for automotive designers. By providing a broad portfolio of ASIL compliant processor IP and software development tools, Synopsys helps designers accelerate the development and qualification of their safety-critical automotive SoCs.”
