This paper describes research carried out using a quadded logic cell (QLC) structure with the purpose of creating a fault tolerant strategy for stuck-at faults. In order to create the tolerant built-in behaviour, the basic logic elements must have re... Read More about Fault Tolerant Quadded Logic Cell Structure with Built-in Adaptive Time Redundancy.

Self-healing Fuel Pump Controller Mapped into Memory Based Finite State Machine (2014)
Journal Article

This paper describes our on-going research into the design of finite state machines (FSMs) that exhibit self-healing characteristics. The approach adopted here is based on conversion of the traditionally adopted logic hardware design into generic loo...
