Testing and verification is indispensable in a safety-critical environment to ensure that systems behave and communicate as intended in a network with high-reliability requirements. TTTech's AFDXEnd System Test transmits system-critical and safety-critical data in a secure way and according to a predefined allocation of bandwidth. The equipment supports simulation, scripting, and fault injection (MAC level faults, skew), as well as enhanced data capturing and replaying. It is compatible with IEEE 802.3 Ethernet and enables data traffic with a bandwidth of up to 100 Mbit/s.
