We consider the potential to use co-modelling and co-simulation in the design of dependably resilient Cyber-Physical Systems (CPSs). Resilience is widely discussed in the public discourse on CPSs, but has many definitions. We propose the description of system resilience in terms of a multi-attribute profile which may be used as a basis for assessment and trade-off analysis in CPSs. Our profile has a particular focus on description of system recovery behaviour. As a first evaluation of the concept, we present a case study based on a VDM and 20-sim co-model of a small smart grid illustrating causal chains that cross the cyber-physical boundary. An evaluation of the study leads to suggestions forfurther proof-of-concept studies that experiment with increasingly challenging CPS architectures.
