Abstract : This report describes research to improve the capabilities and performance of the Rome Laboratory Intelligent Module Analyzer (IMCMA). (See 'An Architecture for Intelligent Multichip Module Reliability Analysis,' RL-TR-94-71.) IMCAM is a blackboard-based software tool that automatically applies finite-element and knowledge-based analysis to rapidly assess the thermal reliability of microelectronic multichip module (MCM) designs. IMCMA is a cooperative effort that involves Rome Laboratory, the Mechanical Engineering and Computer Science Departments at the University of Massachusetts, and Blackboard Technology Group, Inc. In IMCMA, the amount of modeling effort and expertise required of the designer has been reduced through: (1) the use of a high-level representation of devices as the interface between the designer and the analysis tools; and (2) incorporating the modeling and analysis expertise of experienced design analysts into the software, making it available to less experienced designers. In this effort, the previous architecture was extended to represent finite-element mesh objects and results directly on the blackboard, and to provide separate MCM defined and 'as modeled' descriptions. In addition, graphical facilities for editing and displaying MCM descriptions and material specifications were developed along with an improved interactive display of the analysis results.
