Hardware Implementation Pane

The Hardware Implementation category includes parameters for configuring a hardware board to run a model. Hardware implementation parameters specify different options for building models to run on hardware boards or devices including communication connections and hardware specific parameters. Hardware Implementation pane parameters do not control hardware or compiler behavior. The parameters describe hardware and compiler properties for the MATLAB^® software.

Specifying hardware characteristics enables simulation of the model to detect error conditions that can arise when executing code, such as hardware overflow.
MATLAB uses the information to generate code for the platform that runs as efficiently as possible. MATLAB software also uses the information to give bit-true agreement for the results of integer and fixed-point operations in simulation and generated code.

Parameter	Description
