Now we have described how to control ADTF, but our main concern is to transfer data, synchronize time and work deterministically across computer boundaries.
For this purpose we developed ADTF components to embed the
FEP functionality in the ADTF Filter Graph. So that we can describe the boundaries of our ADTF Session and what signals and clocks can be used from outside.
FEP Sink and
FEP Source give access to the topics/signals from the simulation bus.
The smallest execution unit in
FEP is a
fep3::arya::IJobRegistry::IJob. A Job will be registered at the active scheduler and executed according to its scheduling mechanism.
If you want ADTF to behave as a deterministic component in the distributed system you need to replace your usually used ADTF Timer Runner with a
FEP Job Runner.
This guarantees that all ADTF Filters and other ADTF Components are executed in a synchronized way related to the other
FEP Participants of the
FEP System and therefore behave deterministically.
FEP Timing Service is the ADTF component responsible for the integration of the
FEP timing with ADTF. The service will register one clock at ADTF and one at the
FEP Participant of the ADTF session.
The service needs to operate in
FEP clock adtf_stream_clock_master will make the stream time of ADTF available to other
FEP Participants. Also it will forward events from the Harddisk Player to the slave
The clock is only used if the ADTF session is the timing master of the
The ADTF clock fep_synchronized_clock will make the time of the
FEP Participant available within ADTF by being registered as the current stream clock of the ADTF clock service.
The clock is only used if the ADTF session is a timing slave within the
FEP Timing Service. You only need to configure the
FEP Systemusing one of the following adtf_control commands.
FEP Participantsyou need to add the
FEP Timing Serviceto your session and configure timing using one of the
ADTF as a Framework provides several options and is extendable. The architecture is very common and provides a lot of possibilities to fulfill these requirements.
The job of our toolset is to provide the user convenience and automatization for that - of course also for using
FEP within ADTF.
You can use the context menu to launch an ADTF Session as
FEP Participant directly from the ADTF Configuration Editor in the two ways we described in the last guide:
We plan to expand the ADTF Configuration Editor so that it not only supports the creation of signals, but should also be able to display, configure and manage a entire
So stay tuned for a lot more improvements the upcoming ADTF releases!
FEP is integrated in the
All components based on the
adtf::remotesdk can now be addressed via
FEP System. For example you can use the ADTF Status Monitor with the url
Another tool could be the ADTF Logview.
The next guide will tell how you can set up a time synchronized
