A fault tolerant incremental design methodology
2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003Incremental design is the widest applied methodology for VLSI design since, it allows one to produce early versions of the system that, even if not satisfying all requirements, allow one to verify its applicability in the field. The migration from, a system version to a more powerful one is based on the substitution of a module with a more powerful ...

Design of a Fault Tolerant FPGA
2000In this paper we introduce our fault tolerant FPGA and explain the fault tolerant features of our FPGA. They result from the block structure, the cell structure, and the intrablock routing along with a global state machine for testing. The state machine along with comparator detects single stuck-at-zero/one faults in the cell structure and mask them on

Designing software components to tolerances
ACM SIGSOFT Software Engineering Notes, 2007Many traditional engineering designs, other than software, depend on the physical properties of components. Those properties enable the engineer to specify precise tolerances between those components. Software components are abstractions with no inherent physical properties. The absence of physical properties makes it more difficult, but not impossible,

A design method for skew tolerant latch design
APCCAS 2008 - 2008 IEEE Asia Pacific Conference on Circuits and Systems, 2008This paper describes a new design method for skew-tolerant latch design (STLD) and evaluation on a commercial chip design. The conventional edge-triggered flip-flop (FF) design methods using clock synchronization are very practical, since only the timing constraints defined by a given clock frequency are optimized. However, clock skew that has a strong

Can design faults be tolerated?
Software & Microsystems, 1984The short answer to the question posed by the title is “Yes”. A more cautious, and less simplistic, response would be that in certain circumstances, with appropriate provision of redundancy and allied supporting mechanisms, it is certainly possible to provide a measure of tolerance to faults of design.

Tolerance design: Choosing optimal tolerance specifications in the design of machined parts
Quality and Reliability Engineering International, 1994AbstractThis paper provides a general approach for determining tolerances for machined parts which minimizes the combined machining cost and quality cost. We derive a mathematical model which takes into consideration both machining cost and quality cost, which depend on tolerance specifications and the distribution of the machined part dimension ...

Design of Tolerances for Quality
6th International Conference on Design Theory and Methodology, 1994Abstract Design of a product (process) includes system design, parameter design, and tolerance design. Robust design is closely applicable to parameter design and tolerance design. The current literature on robust design is focused on parameter design while little attention has been paid to tolerance design.

Technical drawings are constituted by three components that are strongly correlated: the geometry showing the part shape, the dimensions defining the part volume and the tolerances establishing the variability of the two previously described components.

Reliability Engineering & System Safety, 1991
Abstract Typical software fault tolerance techniques are modeled on successful hardware fault tolerance techniques. The software fault tolerance techniques rely on design redundancy to tolerate residual design faults in the software; the hardware fault tolerance techniques rely on component redundancy to tolerate physical degradation in the hardware.

Designing masking fault-tolerance via nonmasking fault-tolerance
IEEE Transactions on Software Engineering, 1998Masking fault-tolerance guarantees that programs continually satisfy their specification in the presence of faults. By way of contrast, nonmasking fault-tolerance does not guarantee as much: it merely guarantees that when faults stop occurring, program executions converge to states from where programs continually (re)satisfy their specification.
