1. A computer-implemented method for applying a coding standard to a simulatable graphical model in a graphical modeling environment, the method comprising the steps of: providing a coding standard in the graphical modeling environment; applying the coding standard to the simulatable graphical model to detect violations of the coding standard in the simulatable graphical model; displaying violating segments of the simulatable graphical model differently than non-violating segments of the simulatable graphical model; and in response to users' selection of a selected one of violating segments, displaying information on a violation of the coding standard in the selected violating segment.
