Abstract

Faults will be a great challenge in modern VLSI circuits. Different faults are injected into the VHDL model of a commercial microcontroller and their effects have been compared. Bridging fault and stuck-at faults are injected. The methodology used is VHDL based fault injection technique, which allows an exhaustive analysis of the influence of different fault models and system parameters. Fault models are used at logic and RTL levels. From the simulation result, the occurrences of failures and have been found out. Fault coverage and test coverage are found out using DFT compiler and Tetramax tool.
