Examine potential strategies and identify issues related to integrating CALCE Software with
commercially available computer-aided design and computer-aided manufacturing
(CAD/CAM) tools.
Background
With the move to UNIX, an opportunity exists to provide some level of integration between
the CALCE Software and commercially available CAD/CAM tools. During the past year,
the software group investigated extracting data from Gerber artwork files. Unfortunately, the
loss of information in the creation of Gerber files made this approach unattractive. Early
examination of a Mentor neutral file holds some promise, but some modifications may be
necessary. This project will continue this examination.
Approach
The project will be initiated by examining standard electronic data exchange files produced by
leading CAD/CAM tools. This will involve working with select companies. During the year,
we will examine ISO-10303-210 and related documents, as well as neutral files from Mentor
and Cadence. An effort will be focused on extracting trace information for improving the
corrosion assessment tool. As part of this study, the CALCE modeling tools will be
examined to ways of improving data transfer and increasing analysis capabilities.
Recommendations will be established for potential software design changes. Preliminary
coding will be preformed to examine the feasibility of proposed changes.
Work Accomplished
Mentor framework has been selected to the integration study. Meetings have been held
between CALCE and Mentor.
A Mentor translator has been developed. This tool works with the current CALCE
import/export functions discussed in the CALCE Interface Guide. This tool is available with
source code to any member.
Modified CALCE PWA Toolbox to include Mentor Import Facility.
Developed Parts tool to modify and add auxiliary information need to perform CALCE
Physics of Failure Assessment.
Deployed system to AlliedSignal and Lockheed-Martin. Field tested system with a
variety of Mentor Designs.
