This chapter describes the application of VLASIC for analyzing the effects of adding redundancy to a design. Redundancy analysis is accomplished by means of a post-processor that uses the chip fault lists generated by VLASIC and a description of chip redundancy to predict yield in the presence of redundancy. We first discuss previous work in predicting

Redundancy in Organizational Systems
Social Service Review, 1992In this article, I provide a basic introduction to the concepts and theory of redundancy in organizational systems. The roots of redundancy are explored, and four different types of redundancy are identified and discussed. Assumptions underlying both redundant and nonredundant systems are examined. I also review some of the criticisms of redundancy and

A Review of Standby Redundant Systems
IEEE Transactions on Reliability, 1980This article critically reviews the existing literature on standby redundant systems. Concepts related to standby systems have been defined. Parameters in which system designers and engineers may be interested have been discussed. Some of these parameters are mean-time-to-system failure, s-expected number of visits to a state, steady-state availability,

Synchronization and Matching in Redundant Systems
IEEE Transactions on Computers, 1978Most of the published work on massive redundancy makes one crucial assumption: the redundant modules are synchronized. There are three ways of achieving synchronization in redundant systems-independent accurate clocks, a common external reference, and mutual feedback.

Annual Reliability and Maintainability Symposium. 2001 Proceedings. International Symposium on Product Quality and Integrity (Cat. No.01CH37179), 2002
This paper's intent is to present a new approach for enhancing system reliability by utilizing the ability of certain systems to tolerate interruptions in their basic function for a specific period of time without violation the mission success definition.

ACTIVE REDUNDANCY ALLOCATIONS IN SERIES SYSTEMS
Probability in the Engineering and Informational Sciences, 2011We consider the problem of optimally allocating one/two active spares in series systems. Lifetimes of different configurations are compared with respect to the reversed failure rate order, the failure rate order, the increasing concave order, and the stochastic precedence order.

Confidence Limits for Redundant-System Availability
IEEE Transactions on Reliability, 1976s-Confidence limits are established for the Availability of a standby redundant system (1-out-of-N:G system) for both hot and cold spares consisting of several identical units and repair facilities. The failure and repair rates of the units are s-independent, constant, and estimated from test data.

Active Redundancy Allocation in Coherent Systems
Probability in the Engineering and Informational Sciences, 1988We introduce in this paper a new measure of component importance, called redundancy importance, in coherent systems. It is a measure of importance for the situation in which an active redundancy is to be made in a coherent system. This measure of component importance is compared with both the (Birnbaum) reliability importance and the structural ...

Cryptographic systems using redundancy
IEEE Transactions on Information Theory, 1990The problem of ensuring recoverability of encrypting data in a file storage system is examined. In this situation, the original data (plaintext) are removed from the system after encryption. In the event of errors either in the initial processing or in the storage of the data, the file may be rendered unrecoverable.

Multiple-Unit Standby Redundant Repairable System
IEEE Transactions on Reliability, 1981Two models of n-unit standby redundant repairable systems are considered. Identifying suitable regeneration points, expressions for the Laplace transform of the following are obtained: availability; reliability; interval reliability; and s-expected number of visits to any state, repair completions, failures, system downs, system recoveries, and s ...
