Abstract: An integrated Vehicle Electrical Design and analysis System (VEDS) which is adapted to accommodate data interchanged between multiple vendor-independent Computer Aided Engineering (CAE) tools. The system includes a Vehicle Database (VDB) which is operative as a central repository to store all design, analysis and library information. The VDB is interfaced and data is exchanged with the CAE tools through an interface which is predominantly object-oriented using Common Lisp Object System (CLOS). For each tool, an outbound translator is operative to translate the tool's internal data structures into a standard interchange format. Similarly, for each tool, an inbound translator is operative to translate a standard or tool specific interchange format into the tool's internal data structures. The VDB also includes an inbound and an outbound translator. The inbound translator is operative to load data structures from each of the CAE tools into the VDB.
