Avionics Full-Duplex Switched Ethernet (AFDX) Verification

Executive Summary

The client, a US-based tier-1 aerospace supplier wanted to achieve time-bound verification of compliance for its legacy in-flight communication system software based on DO-178B DALC A compliance. This in-flight communication system was based on a Power PC platform and had multiple communication protocols, including ARINC 664, ARINC 615A, 665-2, 665-3. The company was looking for a verification partner with a prior experience in aerospace certification with DAL A compliance to help with a system-level verification and validation.

eInfochips took the complete ownership of software verification and system validation of the client’s AFDX (Avionics Full-Duplex Switched Ethernet) switch. eInfochips also supported regulatory audits with FAA (Federal Aviation Administration), EASA (European Aviation Safety Agency), and Transport Canada for software certification of three different product variants. This helped in porting legacy test procedures and tool obsolescence management.
