} The goal of the project is to establish a design flow in system and RT levels for dependable digital VLSI. We will define models errors and indexes of dependability, and develop techniques to evaluate the indexes and to improve them. We will implement the techniques as design and analysis tools, and combine the tools into an existing design flow to make a prototype of design flow in which designers can consider tradeoffs among cost, performance, power consumption and dependability.

} We establish an efficient design flow to analyze tolerance of soft error which become high risk due to neutron or alpha particles in very deep submicron.
Products: A tool chain to analyze stochastically soft error rate and to estimate soft error tolerance of circuits in system level to circuit level based on device characteristics of cells obtained by device level analysis.
Tool Chain Charactaristics: Analysis of soft error tolerance for huge system with some hundred million transistors based on device characteristics obtained by conventional device simulator in efficient time.
Contributions: 1. Designers can estimate soft error tolerance in system and RT level for digital VLSI and consider tradeoffs among cost, performance, power consumption and dependability.
2. Quantitative estimation of soft error tolerance for applications which require high dependability such as airplane and automotive. (Stress test for digital VLSIs)
3. It is an important issue that we build consensus on use of proposed techniques among VLSI users in industry segment.
