Collaboration looks to accelerate functional safety development for RISC-V

2 mins read

IAR Systems is partnering with NSITEXE, a group company of DENSO, that develops and sells high-performance semiconductor IP.

The partnership is to focus on bringing high-performance development tools solutions with ensured functional safety and extensive support services to innovative applications based on RISC-V.

Functional safety is a growing requirement for embedded systems, with automotive applications, industrial automation and medical devices as three of the major driving forces.

IAR Systems launched the first edition of its functional safety certified products in 2013 but with the rise of RISC-V technology and its rapid evolution into many different embedded systems designs, functional safety for RISC-V is now becoming more important. In 2020, IAR Systems presented its first functional safety solutions for RISC-V and now, together wth NSITEXE, it is looking to further expand the possibilities for companies choosing RISC-V.

Recently announced, NSITEXE launched the NS31A, a general-purpose CPU with a single-issue core with a 4-stage in-order pipeline that uses a 32-bit RISC-V ISA (RV32IMAF). It supports ISO 26262 ASIL D functional safety mechanism required for automotive applications, and also supports a privileged mode which is required by the AUTOSAR Platform.

“At NSITEXE, development efforts have been focused on three pillars - versatility, efficiency, and functional safety - with massive future trends in mind,” commented Hideki Sugimoto, CTO, NSITEXE. ”The NS31A implements these as a RISC-V 32-bits general-purpose CPU with high functional safety for users who want to control embedded systems easily, reasonably, and safely. IAR Embedded Workbench for RISC-V will be the must-use software development tools in the market of RISC-V, and IAR Embedded Workbench for RISC-V and NS31A will be a leading solution for customers who develop safety-related applications.”

“This collaboration brings our joint strong technology and services further into the RISC-V community with extended possibilities for functional safety development,” added Stefan Skarin, CEO, IAR Systems. “IAR Systems’ functional safety offering provides the widest standards coverage in the industry, and together with NSITEXE, we are now enabling companies to speed up the path of using RISC-V in applications where ensured safety is critical for success.”

For companies with requirements on functional safety, IAR Systems offers functional safety editions of its complete development toolchain IAR Embedded Workbench. The certified tools are complemented with a special Functional Safety Support and Update Agreement with guaranteed support for the sold version for the longevity of the contract as well as prioritised technical support.

The functional safety edition of IAR Embedded Workbench for RISC-V is certified by TÜV SÜD according to the requirements of IEC 61508, the international umbrella standard for functional safety, as well as ISO 26262, which is used for automotive safety-related systems. In addition, the certification covers IEC 62304, EN 50128, EN 50657, IEC 60730, ISO 13849, IEC 62061, IEC 61511 and ISO 25119.
