HCC Embedded offers an off-the-shelf TCP/IPv4 network stack that complies with the ISO 26262 Automotive Safety Integrity Level (ASIL) B standard for use in automotive systems. The embedded software vendor is using the Safety Elements out of Context (SEooC) approach that originated in ISO 26262-10 to build reusable software elements, the first of which is its SafeTCPIP commercial network stack.

SEooC is a safety-related element that that is developed out of context to provide a specific function with no awareness of how it will be used in the target system. The defacto network standard for connected cars and in-vehicle safety systems is TCP/IP, but commercially available products are not typically designed to meet safety standards, are only partially certified, or are tightly integrated with a single vendor’s development system and RTOS.

SafeTCPIP follows the ISO 26262 V-model development process and offers automotive OEMs and suppliers an off-the-shelf solution that has been independently designed to satisfy TCP/IP networking. The reusability of the stack contributes to long-term stability and reduces development costs. Future releases will map the standard ISO 26262 V-model process to other safety-critical standards, such as those used in aerospace, industrial, and medical device markets.
