SiFive and IAR Collaborate to Advance the Automotive Ecosystem and Drive RISC-V Innovation in Automotive Electronics

Shanghai, China – December 15 , 2025 – SiFive, the gold standard for RISC-V, and IAR, a global leader in embedded development software, today announced the full support of IAR toolchain for SiFive’s Automotive IP cores. With the latest release of Embedded Workbench for RISC-V v3.40.2, IAR expands its support from the E6-A series to include the SiFive Essential™ E7-A and S7-A series products, providing automotive developers with a complete, commercial-grade solution that accelerates time-to-market.

SiFive Automotive Solutions: The Core of Performance and Safety

SiFive Automotive RISC-V IP has achieved ISO 26262:2018, IEC61508:2010 and ISO/SAE 21434:2021 certifications across both its 32-bit E Series and 64-bit S Series. The E6-A series supports real-time and safety-critical applications:

• E6-AB provides ASIL B hardware safety for real-time workloads
• E6-AD targets advanced driver-assistance systems (ADAS)
• E6-AS offers split-lock capability for configurable lock-step and non-lock-step modes, enabling ASIL D when in lock-step The new Essential E7-AD and E7-AS products are also 32-bit, providing 30% higher performance than E6 series. The 64-bit S7-AD delivers high-performance functional safety for domain controllers, safety islands, and other demanding automotive systems.

IAR Embedded Workbench for RISC-V: The Trusted Toolchain for Robust Application Development

IAR Embedded Workbench is a leading commercial embedded development toolchain, known for powerful code optimization and a highly reliable environment. Optimized for the RISC-V architecture, the latest v3.40.2 release integrates a high-performance compiler, debugger, and the C-STAT static analysis tool, helping teams enforce standards such as MISRA C/C++ and strengthen the safety and reliability of SiFive Automotive-grade IP–based applications.

As part of the IAR embedded development platform, the toolchain seamlessly connects with modern workflows, including CI/CD, cloud licensing, and automated debug and test, supporting scalable development across safety-critical automotive programs. A TÜV SÜD-certified functional safety edition is also available, compliant with ISO 26262 and other automotive standards, ensuring certified development assurance for safety-critical systems including intelligent driving and advanced cockpit applications.

“As the company founded by the inventors of RISC-V, SiFive is driving rapid RISC-V adoption across industries, including automotive. We delivered our first automotive products in 2022, and all three series are now broadly adopted by commercial customers. Through close collaboration with partners like IAR, we provide comprehensive system-level solutions. IAR’s comprehensive support for SiFive Essential Cores and Automotive IP accelerates integration for emerging automotive applications.” said John Ronco, Senior Vice President of Products at SiFive.

“We have been deeply engaged in the RISC-V ecosystem since its early stages, and our long-term collaboration with SiFive reflects that commitment. As RISC-V adoption expands in automotive, the latest IAR tools now fully support SiFive’s Automotive IP. Together, we empower customers to leverage high-performance RISC-V cores in intelligent driving, digital cockpit, and other safety-critical systems with reliable toolchain support and safety assurance.” said Thomas Andersson, Chief Product Officer at IAR.

As advanced, safety-certified IP and a mature, reliable toolchain come together, RISC-V automotive developers now have a stronger and more trusted platform to accelerate innovation across electrification and intelligent mobility.
