fmdtools (Fault Model Design tools) is a toolkit for modelling system resilience in the early design phase. With it, one can simulate the effects of faults in a system to build resilience into the system design at a high level. To achieve this, fmdtools provides a Python-based design environment where one can represent the system in a model, simulate the resilience of the model to faults, and analyze the resulting model responses to iteratively improve the resilience of the design.
