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.

Selective Access and Editing in a Database

Ames Research Center, Moffett Field, California A complex organization with many tasks and sub-tasks, many phases, and many workers often will have an associated database with many users and groups, each of whom has a limited “need to know” (e.g. fine-grained security access controls) that does not extend to all information in the database. A group of users having access to information in a particular portion of the database may need to edit one or more documents to restate the original information more conveniently or accurately.

Integrated Science Instrument Module (ISIM) Reconfigurable Packet Tool

Goddard Space Flight Center, Greenbelt, Maryland This tool supports the development of table loads required to inform the flight software of new on-the-fly packet definitions. The main outcome of the processing includes all the database products needed by the ground system to process the newly created packets. The tool ingests the latest telemetry definition from the James Webb Space Telescope (JWST) central database repository, and updates those definitions as required to support the dynamic packet definitions determined by the user of the tool. These updated telemetry definitions are in a form that can be directly sent to the JWST central database repository for inclusion in a new database version. The tool allows for the inclusion in the new packet definitions of any ISIM Flight Software (FSW) data types.

Bug View

Ames Research Center, Moffett Field, California This hardware-independent, Web-based service provides the capabilities to improve software assurance by streamlining the management of the analysis tools, the code being analyzed, and the results that are generated. The service is a GUI (graphical user interface) application that addresses the needs of software developers and supporting analysts by presenting a single interface from which multiple static code analysis tools can be configured and executed. It also provides the means to automate consistent periodic analysis of each release of code, has the capability to track code change and identified issues in the code through progressive build releases, and provides tools for identifying and rejecting false-positives from results while identifying quickly what the real issues are within the source code.

Program Determines When MRO Observations Span More Than One Spacecraft Sequencing Period

NASA’s Jet Propulsion Laboratory, Pasadena, California Previously, the Mars Reconnaissance Orbiter (MRO) did not allow observations to go beyond the end of a planning period. However, opportunities for observing the Mars Science Laboratory (MSL) rover occur close enough to these boundaries to require the observations that support the rover to cross these boundaries. This requires the observation to be included in two planning cycles.
