What is Wiring Synthesis?

Wiring synthesis is a transformative technology for vehicle wiring design. Using principles of Model Driven Systems Engineering (MDSE), wiring synthesis automatically generates detailed vehicle wiring design data from simpler, higher level inputs. Totally different from traditional wire routing, wiring synthesis addresses key domain problems such as high frequency design change, arduous configuration management, design quality and verification, and development cost and cycle time. Supported by ten years of software development, major automotive OEMs and suppliers in Europe, USA and Asia have now applied wiring synthesis technology with great success. As electrical complexity continues to grow, wiring synthesis will become the only practical way to design automotive electrical systems.

Optimizing Automotive Wiring Designs Using Engineering Design Automation

Currently, most methods for optimizing an Electrical Distribution System employ unsophisticated and manual spreadsheet tools. Any detailed feedback on critical metrics such as cost or weight typically relies on another organization and requires weeks or months. The resulting EDS is inevitably sub-optimized, not due to a lack of engineering ability, but rather the tools available. To ensure that the EDS design is optimized from the outset, the design environment itself must be enhanced. This paper will discuss the four key requirements for an EDA system along with the flow implications using examples from the Mentor Graphics Capital suite.

Technology To Speed Wire Harness New Product Introduction

The speed with which wire harness makers can bring new or changed designs into production is a key business differentiator. Up until now, the complex sequence of tasks necessary to accomplish such a feat was poorly supported by COTS software. A robust COTS solution from Mentor Graphics is now available. This paper focuses on a set of manufacturing disciplines and describes key “building blocks” which underpin Mentor’s robust software solution for harness wire manufacturers. The Mentor approach protects company IP, reduces manufacturing engineering costs, improves process quality, and provides early and accurate visibility of gross margins. More importantly, it removes critical path bottlenecks to new product introduction.

Electropolishing for Hydraulics and Pneumatics

Manufacturing components for the hydraulic and pneumatic industries often involve creating the ideal surface finish: neither too rough nor too smooth. When it comes to surface finish, electropolishing can help manufacturers walk that fine line and achieve the ultimate in function.

Hybrid DC Circuit Breaker Based on Cryogenic Technique

This hybrid solution combines mechanical and solid-state technology. John H. Glenn Research Center, Cleveland, Ohio DC protection systems such as circuit breakers play a key enabling role for the DC power system in applications such as aviation, the power grid, and the like. Conventional electromagnetic circuit breakers are a mature technology. However, the large size and high response time make it unsuitable for an electrical system in aviation that requires fast response time. Compared with a mechanical circuit breaker, the solid-state circuit breaker based on high-power semiconductors can provide a fast response time to make the fault current fully controlled. The on resistance of the semiconductors creates high conduction loss, which leads to low efficiency. Therefore, a hybrid solution that combines both mechanical and solid-state technology is desired.

Modular Propulsion and Deployment Electronics System

The new approach is flexible enough to quickly accommodate design changes. Goddard Space Flight Center, Greenbelt, Maryland The Lunar Reconnaissance Orbiter (LRO) required an innovative and modular approach to the design and development of the electronics needed to control the propulsion and deployment components, as well as the electronics necessary to support safety inhibits for personnel and range requirements. Since these electronics would be designed in parallel with the systems they would interface with, they would need to be flexible enough to quickly accommodate ongoing design changes.
