A complete TCP/IP v4 stack for safety-critical automotive, industrial, or medical embedded systems.
Tuxera SafeTCPIP™ is a complete embedded TCP/IP v4 network stack developed to the ISO 26262 Automotive Safety Integrity Level (ASIL) B standard. The stack is suitable for integration with any system that requires a high level of safety-integrity, and is mappable to other standards such as IEC 61508 and ISO 62304.
Certifiable networking stack for safety-critical embedded systems
To guarantee the quality of the networking, automotive software developers may require a certifiable TCP/IP stack for integration into a safety product or environment.
The de facto network standard for connected cars and in-vehicle safety systems is TCP/IP, but commercially available products are rarely developed to meet safety standards, are only partially certified, or are tightly integrated to a single vendor’s development system and RTOS.
Tuxera SafeTCPIP is an independently designed, off-the-shelf networking software stack that fills a critical market for automotive, industrial, or medical applications. It works on virtually all modern microcontrollers, with or without RTOS. Plus it also includes a test suite to validate the RTOS resources required by the network stack.
SafeTCPIP is developed to full ISO 26262 Section 6 processes for integration with automotive systems that require a high safety-integrity level. It is supported by an independent software lifecycle for maintenance. The exact verified product can be maintained and modified to safety standards independent of any other project that integrates SafeTCPIP.
The stack is built as a set of safety elements out of context (SEooC) as defined in ISO 26262-10, and deliverable as a distinct safety project with full life cycle maintenance. The reusability of the TCP/IP stack contributes to long-term stability and reduces development costs.
Reusing embedded software in safety-critical automotive systems
Tuxera uses a safety elements out of context (SEooC) approach to develop reusable software components for systems engineered to meet stringent requirements for safety, quality, and portability.
We’ve invested extensive time and effort in creating the processes and environment required to build reusable SEooCs and have built a full life cycle as a manageable part of our customers’ safety development.
The first element is the SafeTCPIP network stack for use in automotive systems. Future releases map the standard ISO 26262 V-model process to other safety-critical standards such as those used in aerospace, industrial, and medical device markets.
The SEooC approach also allows you to focus on developing the rest of your application or project to the ISO 26262 standard, while we handle the stack building and integration.
