New RISC-V Solution: SAFERTOS for IAR Embedded Workbench for RISC-V

Bristol, UK -

SAFERTOS and IAR Embedded Workbench for RISC-V  are available on the RISC-V board HiFive1 from SiFive to form a compelling RISC-V safety solution. A free, fully functional demo of the solution is available from the WITTENSTEIN high integrity systems website.

SAFERTOS is available integrated with the complete C/C++ compiler and debugger toolchain IAR Embedded Workbench for RISC-V on the HiFive1. This integration is built for safety from the outset, with SAFERTOS available pre-certified to IEC 61508 SIL3 and ISO 26262 ASIL D. RISC-V is an exciting modern Instruction Set Architecture (ISA) with huge possibilities.

SAFERTOS is a pre-emptive, safety critical RTOS from WITTENSTEIN high integrity systems that delivers unprecedented levels of determinism and robustness to embedded systems, whilst using minimal resources. It is used internationally across a range of safety critical applications and is renowned for its high quality. SAFERTOS is available pre-certified to ISO 26262 ASIL D and IEC 61508 SIL 3 by TÜV SÜD. A key advantage of SAFERTOS is the upgrade path from FreeRTOS to SAFERTOS; prototype using FreeRTOS and convert to SAFERTOS at the start of formal development.

The complete C/C++ compiler and debugger toolchain IAR Embedded Workbench for RISC-V offers excellent code optimizations for size and speed.  To ensure code quality, the toolchain includes C-STAT® for integrated static code analysis. C-STAT can help prove compliance with specific standards like MISRA C:2004, MISRA C++:2008 and MISRA C:2012, as well as detect defects, bugs, and security vulnerabilities as defined by the Common Weakness Enumeration (CWE) and a subset of CERT C/C++. Future releases of the toolchain will include functional safety certification.

RISC-V is an ambitious programme to develop a free and open universal Instruction Set Architecture that is suitable for all processors, from small embedded microcontrollers to fast high performance computers.

“SAFERTOS and IAR Embedded Workbench form a compelling solution on this exciting ISA.” Says Steve Ridley, Engineering Leader at WITTENSTEIN high integrity systems, “We are experiencing significant engagements from our customers, and I look forward to the continued evolution of RISC-V.”

”We are happy to see this integration of SAFERTOS and IAR Embedded Workbench for RISC-V as it enables new possibilities for the RISC-V developer community,” says Anders Holmberg, Chief Strategy Officer, IAR Systems. “IAR Systems launched high-quality professional tools for RISC-V in 2019 and we plan to continue playing an active role in the RISC-V space in 2020 and forward.”
