SOME/IP decoding

In this guide you will learn, how the SOME/IP Message Extractor, the SOME/IP Substream Decoder, the PCap Ethernet Receiver, , the Vector Ethernet Receiver, the SOME/IP Service and the SOME/IP Trace View are working. After reading this guide, you will know:

For passing this lesson with success, you should have finished followed tutorials from the ADTF3 Guides:

PCap Ethernet Receiver


The PCap Ethernet Receiver captures the Ethernet network traffic and provide it as Ethernet samples on its output pin. You can choose the ip address of your network adapter in the property variable adapter_ip_address.

Further resources about the PCap Ethernet Receiver:

Vector Ethernet Receiver


The Vector Ethernet Receiver captures Ethernet traffic from devices which use the Vector XL Driver Library. To use this ADTF streaming source you have to set the properties attachment_name, attachment_type and network. This properties correspond with the properties of the Vector Hardware Config Tool.

SOME/IP Message Extractor Filter


The SOME/IP Message Extractor extracts SOME/IP content from the raw Ethernet samples and provide it as SOME/IP samples on its output pin.

SOME/IP Substream Decoder


The SOME/IP Substream Decoder decodes the content of the SOME/IP samples and offers the SOME/IP messages as single substreams as its output.

SOME/IP Service


The SOME/IP Service is responsible for loading a SOME/IP database and providing access to the ISomeIpDatabase contained within. The service also handles the creaton of ISomeIpDecoder instances for convenient access of SOME/IP samples. The information needed are normally inside ARXML-files. So you need the SOME/IP ARXML Parser Service which is located inside the ARXML Toolbox. This service is automatically added when you add the SOME/IP Service.

SOME/IP Trace View


The SOME/IP Trace View shows the SOME/IP Messages of a selectable sample stream. You can choose the sample stream in a drop-down menu within runtime.

Typical SOME/IP filter chain in ADTF

Normally you have an ADTF streaming source where the Ethernet data is produced. This could be an ADTF DAT File Player or PCap Ethernet Source or the Vector Ethernet Receiver or something else which collects Ethernet data. The next filter is the SOME/IP Message Extractor which extracts SOME/IP content from the raw Ethernet samples. The last filter is the SOME/IP Substream Decoder, where the SOME/IP messages are offered as substreams. For the connection information you use an ARXML which you include in the SOME/IP Service. To inspect your SOME/IP messages you can include a SOME/IP Trace View.
