A Fast and Flexible Platform for Fault Injection and Evaluation in Verilog-Based Simulations

This paper presents a complete framework for Verilog-based fault injection and evaluation. In contrast to existing approaches, the proposed solution is the first one based on the Verilog programming interface (VPI). Due to standardization of the VPI, the framework is-in contrast to simulator command based techniques-independent from the used simulator. Additionally, it does not require recompilation for different fault injection experiments like techniques modifying the Verilog code for fault injection. The feasibility of the VPI-based approach is shown in a case study.
