The comprehensive approach of PREEvision supports a communication design based on the logical or software architecture and the network topology. However, in some application scenarios the communication shall be designed without the relevant logical or software architecture.  

The communication design explorer in PREEvision 10.0 closes this gap: You can now develop a communication design without a logical or software architecture and assign receive and transmit relations manually to signals. These relations can be assigned to ECUs (ECU based use case) or to network management nodes (NM) in case the communication is based on NM. The explorer supports the design both of signals and system signals.  

A dedicated perspective is the starting point for the communication design providing a focused user interface. The communication design explorer groups all the tables and tools needed for the design following a clear and streamlined workflow for efficient modeling. The creation of the needed communication infrastructure, communication clusters per bus system and network management are simplified or even synthesized. Consistency checks help creating a valid and AUTOSAR-compliant model.

PREEvision offers a new modeling layer for diagnostic data. Here, the objects for diagnostic specifications can be defined including diagnostic identifiers (DIDs), I/O controls, routines, diagnostic trouble codes (DTCs) and event handling.

The integrated approach of PREEvision secures consistency of the data and prevents redundancies. The diagnostics explorer in PREEvision 10.0 leads users through all relevant design steps and provides dedicated tables for all diagnostic artifacts.
