Electrical System, Wiring and Harness
Top-Down Design Flow
The top-down methodology employed in SaberES Designer for synthesis automation of system integration provides a platform for design and automation verification. SaberES Designer is a database driven design flow where corporate-wide libraries provide predefined part sets for the following design types:
- Sub-System Design - Reusable schematics with logical connections that represent a function (External lights, braking, engine control, etc.)
- System Design - A vehicle projects Sub-System Designs are selected and used to build and synthesize the system design
- Wiring Design - Generated from the System Design and evolved by assigning physical objects such as wires, shells, inline connectors, etc.
- Bundle Design - Generates 2D production harness drawings
Having one electric system design database ensures system integration will be correct and robust for fast, accurate releases.
Sub-System Design
Sub-System Designs (SSDs) are reusable schematics with logical connections that represent a function (External lights, Braking, Engine control etc.). SSDs are created based on the specifications determined by the function and stored in Sub-System libraries.
- Electric components are placed from the libraries that also can contain a hardware model to be used to simulate the function
- Connectivity is created and defined using signals from database
System Design
SSDs are used to build and synthesize the System Design for a series of vehicle projects including ‘excluding functions’. System Design is not about adding data, but about the integration of functions.
- Data networks topologies are created and can be evaluated
- Electrical options are configured for the complete project
Wiring Design
The Wiring Schematic Design is generated from the System Design by adding the ‘excluding options’ like LHD and RHD. Users can assign physical objects from a corporate database including: wires, shells, inline connectors, etc. Using SaberES Designer’s ‘Connector Manager Viewer’, users can partition a design into harnesses and quickly ensure correct inline cavity assignments across the complete vehicle. The ‘Assembly Library’ can be used to build filters for each unique buildable product with the ‘Assembly Library’.
- Your physical wiring system can now be simulated to optimize it against the requirement to stay away from over engineering use pre-defined test benches
- Connections with the 3D MCAD tools (Catia, Creo and NX) will get BoM filtered for each vehicle configurations
Bundle Design
A top-down design flow generates the harness drawing using data from the previous level. SaberES Designer Wiring Design is ideal for electrical objects (wires, connectors etc.) and connectivity in Bundle Design (no intermediate formats).
- MCAD files containing the 3D routing can be imported and used to automate the creation of the harness drawings
- Multiple formats are supported to export your harness data to manufacturing that can be used to create formboards, cut and crimp data etc...
