Phase 1: Network design
In the first development phase, the manufacturer speci-
fies the complete CAN network and defines the communication between the indi-
vidual nodes. This design can be simulated in CANoe in its entirety, which lets
developers verify that specifications regarding bus load and latency times are adhe-
red to (See Fig.
6.20
upper section).
Phase 2: ECU development
In the second phase, the system description is pro-
vided to ECU suppliers as an executable specification. The supplier's developers
can now check the communication behaviour of the SUT using the remaining bus
simulation (See Fig.
6.20
middle section).
Phase 3: System integration
In the third development phase, the manufacturer
integrates ECUs from different suppliers one by one to form the overall system.
The simulated ECUs are now switched off and CANoe is used to test the real CAN
communication (See Fig.
6.20
lower section).
