Computer-Aided Engineering Software for Advanced Workstations in the CIM Environment

Objective

The objective of this project was to develop an enhanced CAD environment (ACCORD) for performing design analyses for CIM in the electronics industry.
Three research paths have been explored in particular:
-integration of a range of design and analysis tools into a coherent computer environment
-computerisation of engineering expertise, thereby aiding the analyst to work faster, more reliable and comprehensive
-computational speed-up aiming at truly interactive analysis.
The work concentrated on the development and implementation of:
-APPEAL (ACCORD Parallel Processing Engineering Analysis Library): a software development that provides improved performance on vector computers for the computationally intensive linear algebra that arises when solving large unstructured sparse matrix eq uations. This has been achieved by designing a new data structure which is suitable for vector computers and restructuring the code to benefit from the architecture of the computer.
-ASSET (ACCORD Suite of Software Engineering Tools): a software package integrating three engineering disciplines - reliability, cost and thermal analysis - under a common management system to perform analyses to evaluate ranges of design options for imp roving functionalities and reducing costs. ASSET's objective was to improve computer-aided engineering by making design assurance an integral part of the design process.
The objective of this project was to develop an enhanced computer aided design (CAD) environment (ACCORD) for performing design analyses for computer integrated manufacture (CIM) in the electronics industry. 3 research paths have been explored in particular: integration of a range of design and analysis tools into a coherent computer environment, computerisation of engineering expertise, thereby aiding the analyst to work faster, more reliably and comprehensively and computational speed up aiming at truly interactive analysis.
The work concentrated on the development and implementation of APPEAL (ACCORD parallel processing engineering analysis library) and ASSET (ACCORD suite of software engineering tools). The APPEAL library contains 4 categories of routines: matrix, vector and scalar operations, performing the normal matrix and vector operations; linear solvers, which are all gradient style solvers; matrix assembly, aggregating contributions to form the final matrix equation for solution; and utilities, which intialize the library constants and handle data conversions and errors. The APPEAL library has a reference code that has been tested on a number of vector computers and, in particular, has been customized for the FPS M64 and the IBM 3090. The reference code contains the newly designed data structure and all the coding nuances that aid vector computations.
ASSET aimed to achieve its objectives through the encapsulation of engineering expertise and the integration of design assurance tools. Its main elements are: an executive manager, domain managers, libraries of technical knowledge and data, a set of analysis tools, a major knowledge based reliability component (ADVISE) and a product analysis database. All the software packages within ASSET can be used as separated tools or in any one of a number of combinations.

The reference code contains the newly designed data structure and all the coding nuancesthat aid vector computations; however, further improvements are possible for a given architecture by additional coding changes and implementing the fast assembler code provided by the computer vendor.

Demonstration prototypes for both APPEAL and ASSET are running successfully. Some improvements of the demonstrations have also been made.
This project will strongly promote the use of advanced analysis tools and methods within the designer and analyst community in the electronics industry.
