“…A VHDL based fault injection tool has been described in [14] and its effectiveness verifi ed through various fault injection experiments carried out using different parameters. During the fault injection campaign, a wide range of transient and permanent faults have been injected through the tool for the signals and variables of the chosen model using simulator commands.…”

The paper unveils a black box model-based self healing strategy to suppress the ill effects of stuck-at-faults occurring in combinational circuits. The primary theory endeavours to attach a sense of reliability in the performance of digital systems and makes them insensitive to the negative impact of faults present in the system. The proposed methodology employs a dynamic fault tolerant approach to protect digital systems from the incursion of stuck-at-faults and enables the system to come up with fault free outputs. The simulation results affi rm the authenticity of the proposed strategy to cancel out the infl uence of faults and facilitate the system to heal itself. The work utilizes the attributes of an FPGA to demonstrate the practical viability of the proposed approach. The performance analysis endorses the defi nite dominance of the proposed healing scheme over the traditional Triple Modular Redundancy [TMR] in terms of fault coverage and area overhead.

“…Compared with saboteur or mutant, the approach of altering the values of signals and variables has the advantages that there is no redundant components are introduced [9], [13]. Because its implementation is relatively simple, it is more suitable for using at the earlier stage of the dependability design, achieving earlier validation and evaluation of reliability mechanisms [9], [14].…”

“…So far, the fault injection techniques aiming at VHDL model have been widely studied and many systematic tools also have been proposed, such as MEFISTO [9]，VFIT [13]，MEFISTO-L [18]， VERIFY [19]. MEFISTO utilizes the simulator built-in commands to alter the values of signals and variables, thus the realization of fault injection.…”

Abstract. Fault injection is a key step in the validation of fault-tolerant design. This paper introduces a novel simulation-based fault injection method. The proposed method is implemented directly in Test Bench (TB) by modifying the signal values in VHDL model, and the fault type and ratio, transient fault duration and fault injection rate etc. can be easily adjusted according to requirements. It also supports the random fault injection by giving a random distribution. Compared with existing approaches, this simple method that can be designed and used immediately has a better extendibility and a better tailing capability due to the fact that it is field programmable in TB. Fault injection experiment shows that this approach is flexible and easy to use.
