1. A computer implemented method, the method comprising: displaying model representations of a simulatable model of an executable system on a display device, where: the executable system includes a plurality of components, the simulatable model represents relations among the plurality of components of the executable system as functions of time, and the model representations include: a textual representation displayed via a textual viewing interface, a block diagram representation displayed via a block diagram viewing interface, and a three-dimensional representation displayed via a three-dimensional viewing interface; receiving an instruction on behalf of a user, where: the instruction identifies a modification to a selected view of the simulatable model, where the selected view is a view of one of: the textual representation of the simulatable model, the block diagram representation of the simulatable model, and the three-dimensional representation of the simulatable model; concurrently modifying, based on the identified modification, the textual representation, the block diagram representation and the three-dimensional representation of the simulatable model, the concurrently modifying including: synchronously updating one or more of the model representations not included in the selected view, where the synchronous updating occurs dynamically when the model representation of the selected view is modified; and displaying the modified textual representation, the modified block diagram representation and the modified three-dimensional representation of the simulatable model.
