Dynamic Fault Injection Library Method for SystemC AMS

Abstract—This article introduces a fault injection library for SystemC/SystemC AMS, which can be used to dynamically integrate fault structures into any SystemC/SystemC AMS description. The injection is achieved by dynamically reconnecting the netlist at the start of the test case execution without altering the DUT model itself. This method has been successfully validated on a … Read more
