Abstract

Disclosed herein are computer aided design (CAD) techniques to implement a unified data schema and graphical user interface (GUI) to link ECU/devices, in-vehicle communications, and vehicle harness information together with respect to architectural relation, performance relation, and cost relation, and to facilitate a designer'"'"'s understanding and manipulation of this information. The domain-specific information from each domain is converted to objects in this unified data schema and stored in a unified database that is accessible to every domain, so that the impact of the current state in the device domain can be accessed and analyzed by a designer from any domain. This approach enables design data sharing and real-time collaboration between different electrical/electronic (E/E) design domains, thereby facilitating the realization of design data collaboration, design change management, and product lifetime management (PLM) and product data management (PDM) implementation.
