IAR Systems® continues their support for RISC-V automotive CPU IP from SiFive with the IAR Embedded Workbench™ for RISC-V adding support for the latest SiFive automotive E6-A and S7-A product series, which address the needs of automotive applications like infotainment, connectivity, and ADAS. IAR’s complete development toolchain helps embedded software developers at OEMs and suppliers to make full use of the energy efficiency, simplicity, security, and flexibility that RISC-V offers.

RISC-V uses a single instruction set architecture (ISA) across all product offerings increases code portability and can greatly reduce cost and time-to-market also for automotive applications. The SiFive automotive processor families offer a high level of flexibility, with options that enable both area and performance optimization for different integrity levels like ASIL B, ASIL D or mixed criticalities with split-lock, in line with ISO26262. The recently announced E6-A series is aimed at a variety of real-time, 32-bit applications, from system control to hardware security modules (HSMs) and safety islands, and of course standalone in microcontrollers. The new S7-A is a 64-bit, high-performance real-time core perfectly suited to the needs of modern SoC with performant safety islands, requiring both low latency interrupt support and the same 64-bit memory space visibility as the main application CPUs.

IAR Embedded Workbench for RISC-V is a complete development toolchain including the powerful IAR C/C++ Compiler™ and a comprehensive debugger. Customers can generate compact-sized code with best-in-class performance and safety for automotive applications, as the tools come with a comprehensive safety offering. The functional safety edition of IAR Embedded Workbench for RISC-V is certified by TÜV SÜD according to the requirements of several functional safety standards, including ISO 26262 and IEC 61508. To ensure code quality for automotive applications, the seamlessly integrated C-STAT® tool for static code analysis proves code alignment with industry standards like MISRA C:2012, MISRA C++:2008 and MISRA C:2004.

“RISC-V is a modern ISA with a fast-growing ecosystem and brings many power and performance benefits to automotive manufacturers and suppliers. SiFive is combining the best of these in the only end-to-end long-term RISC-V roadmap designed to meet automotive needs today and well into the future”, said Patrick Little, CEO and Chairman, SiFive. “With IAR Systems, we have a strong partner in our ecosystem to further advance the success of RISC-V technology in the automotive industry, too.”

“IAR Systems is a proactive member of the RISC-V community. Our close relationship with SiFive enables us to provide support for their latest CPU IP”, said Anders Holmberg, CTO of IAR Systems. “Accordingly, customers in the automotive industry can take full advantage of developing with our professional tools and accelerate their development processes to achieve faster time to market.”
