Abstract

DURING DEVELOPMENT OF COMPLEX, EMBEDDED COMPUTER SYSTEMS QUANTITATIVE TRADEOFFS OF RELIABILITY AND PERFORMANCE ARE SIGNIFICANT DESIGN CONSIDERATIONS. PHASE I DEMONSTRATED THE FEASIBILITY OF AN INTEGRATED RELIABILITY AND TIMING DESIGN ANALYSIS TOOL WHICH WOULD BE CAPABLE OF PROVIDING QUANTITATIVE DATA. PHASE II WILL ADDRESS TWO TECHNICAL OBJECTIVES: (1) DEVELOP A PROTOTYPE INTEGRATED RELIABILITY AND TIMING DESIGN ANALYSIS TOOL; AND (2) DEMONSTRATE THE UTILITY OF INTEGRATED RELIABILITY/TIMING ANALYSES BY APPLICATION OF THE PROTOTYPE TO REAL-WORLD EXAMPLES. THE PROTOTYPE TOOL WILL BE DEVELOPED BY ADDING THE RELIABILITY REPRESENTATION CONSTRUCTS AND ANALYSES DEFINED IN PHASE I TO AN EXISTING TIMING ANALYSIS TOOL. THE RESULTING PROTOTYPE TOOL WILL HAVE AN ICONIC SYSTEM DESIGN CAPTURE INTERFACE. IN ADDITION TO STANDARD TIMING MEASURES, THE TOOL WILL PRODUCE THREE MEASURES OF RELIABILITY. THE TOOL WILL BE DEMONSTRATED BY APPLICATION TO A LARGE SCALE COMPUTER SYSTEM HAVING STRINGENT RELIABILITY AND TIMING REQUIREMENTS.
