Integrated Electrical System Design

SaberES Designer enables design teams to address these challenges by providing an integrated process for electrical system design from concept to manufacturing. SaberES Designer minimizes data entry, manages complex, system-wide design variants, enables concurrent engineering, maintains data integrity, and allows efficient exchange with 3D CAD systems.


Completely Unified Tool for Electric System Design & Verification

  • Intuitive tool for developing functional and physical electrical system designs
    • Sub-system design; reusable schematics with logical connections that represent a function (External lights, Braking, Engine control etc.)
    • System design; a vehicle project generated from the sub-system designs. Signal and component consistency is automatically merged verified across all subsystem designs in the project
    • Wiring design; generated from system design and evolved by engineers assigning physical objects from corporate database including: wires, shells, inline connectors, splices, etc. Design wide Connector Manager to partition design in harnesses and quickly ensure correct inline cavity occupation
    • Bundle design; generated production harness drawings re-using wiring design, option/variant configuration, and 3D MCAD routing
  • Integrated data flow for electrical system design from concept to manufacturing
    • Interface with the leading 3D MCAD engineering tools
  • Single database ensures correct by construction and eliminates data translation errors
    • Consistency is automatically maintained throughout the complete design process with support to configure options and variants to support all buildable vehicles, independent if they are composite or modular/customer specific harnesses
  • Robust sheet check-in/check-out for efficient concurrent engineering
    • Global design teams work in same project with configurable user roles enable working on different levels and security in the process
  • Built-in and extensible design verification

Accelerate Wiring Harness Design using Harness Architecture

The Harness Architecture feature in SaberES Designer allows you to easily capture your vehicle wiring topology, including all the wiring harness paths and interconnection between various components, to import and re-use them into the downstream design flow. Harness Architecture helps you to create wiring designs in an automated generative approach and reduces the time and cost involved in making wiring designs. Watch this short video for more details.

Verification of Electrical Systems

  • Voltage Drop and Over-current
    • Implement reusable verification simulations using SaberES Designer Experiment Analyzer
    • Built-in DC simulation capabilities to verify voltage drop and overcurrent to determine fuse sizes, cross-sectional areas of all wires and existence of sneak paths
    • Back-annotate simulation data and probe critical nodes to quickly identify problem areas
  • Advanced Transient and Robust Design
    • Optional Saber™ Simulator for transient verification of high-speed systems including vehicle networks.
    • Optional Saber InSpecs to optimize the design for component variations and shifts in operating conditions
  • Functional Safety for Verification of Electrical Systems
    • Quickly select and configure hardware faults directly from the SaberES Designer wiring design
    • Export functional safety simulation results from SaberES Designer Experiment Analyzer to document fault coverage and support functional safety flows
