We present a hybrid representation for modeling of mecha-tronic systems. This representation consists of a linear graph and block diagrams and supports our concept of composable simulation. By composable simulation we mean the ability to automatically generate simulations from individual compo-nent models through manipulation of the corresponding physi-cal components in a CAD system. The approach is based on an augmented system graph that represents the topology of the system. This graph captures all the interactions between dif-ferent energy domains (including rigid-body mechanics, elec-trical, hydraulic, and information technology domains.) This form of virtual prototyping will reduce the design cycle signif-icantly by providing immediate feedback to the designer with minimal intervention of simulation and modeling specialists
