SafeTCP/IP

Developed to ISO 26262 ASIL/B standard for integration with any safety system complete with full process that is mappable to other standards such as IEC61508 and ISO 62304

The stack has been built as a set of SEooCs, Safety Elements out of Context as defined in ISO 26262-10, and deliverable as a distinct safety project with full life cycle maintenance for each customer project.

It has been developed following ISO26262-6 as a formal V-model development with the following core work products:

  • Assumptions (Required for SEooCs)
  • High Level Requirements
  • Functional Requirements
  • Architectural Design
  • Detailed design
  • Fully MISRA compliant C Implementation
  • Verification Test Specification
  • Full MC/DC coverage
  • Validation Test Specification
  • Test harness for complete on-target testing
  • Complete forwards/backwards traceability between requirements, design, implementation and test cases

The initial release of SafeTCP/IP includes the following modules each built to this standard:

  • IPv4
  • TCP
  • UDP
  • Socket
  • ARP
  • Ethernet Interface
  • ICMP
  • IGMP
  • DHCP

SafeTCP/IP can be integrated with almost any RTOS and includes a test suite to validate the RTOS resources required by the stack.

For safety systems that require space separation HCC can provide a solution – full space separation involves a performance trade-off – the degree of space separation can be defined when the stack is ordered.
