GetSomeIpServiceDiscovery¶

ID: BusCheck/Ethernet/GetSomeIpServiceDiscovery

This tracestep template documents the SOME/IP Service Discovery (SD) communication present in an ethernet stream. It uses the SomeIpSd and Udp signals as well as the desired Service ID as input. The output is composed of binary signals for the Offer Service, Find Service, Stop Offer Service, as well as (Stop) Subscribe Eventgroup plus the (Negative) Acknowledgement packets found for the desired Service ID.
