Automatic assignment of signals for a functional model

A device receives information associated with a functional model, and generates the functional model based on the received information and with a technical computing environment (TCE), where the functional model including nodes, inputs, and outputs. The device also automatically detects architecture information from an architecture model associated with the functional model, and automatically assigns, based on the architecture information, at least one signal between two nodes of the functional model, a node and an input of the functional model, or a node and an output of the functional model. The device obtains information for code generation based on the assigned at least one signal, and stores the information for code generation.
