Automatic modifications of high level VHDL descriptions for fault detection or tolerance

ISBN: 0769514715The need for integrated mechanisms providing on-line error detection or fault tolerance is becoming a major concern due to the increasing sensitivity of the circuits to their environment. This paper reports on a tool automating the implementation of such mechanisms by modifying high-level VHDL descriptions. The modifications are compatible with industrial design flows based on commercial synthesis and simulation tools. The results demonstrate the feasibility and the efficiency of the approach
