ACOSAR Introduction

8. ACI Architecture Model, Function, Application, … ACI protocol* (logic)
ACU 1
Key
* Subject to standardization
~ Specification but no standardization
Model, Function, Application, …
Model or Function
Subject to integration with other models or RT systems
ACI control API~ Convencience API, reference implementation will be available, not subject to standardization
ACI protocol*
(logic)
ACI protocol or ACI logic: Defines the sequence and contents of ACI messages to be exchanged between ACUs in order to carry out specified ACI functions. May be monolithic within model or RT system.
ACI communication API* exchange of rx/tx ACI messages
ACU 2
ACI Driver*
ACI driver: Standardize mapping from ACI protocol to transport protocol. Contains no execution logic.
Proprietary or custom API
Media Driver
Media driver: Proprietary or self-written libraries, executables, scripts, etc., directly controls the communication media
Media (e.g. bus)
runs a communication protocol

Advanced Co-Simulation Scenario
ACOSAR moves the co-simulation scenario towards an advanced co-simulation scenario
Test benches, HIL systems or offline simulation platforms which are connected to the communication layer are generalized as a black box, the so call ACU ( advanced co-simulation unit)
