20. A system for applying a coding standard to a simulatable graphical model in a graphical modeling environment, the system comprising: a storage containing at least a coding standard in the graphical modeling environment; a processor configured to: apply the coding standard to the simulatable graphical model in the graphical modeling environment to detect violations of the coding standard in the simulatable graphical model; and a display device configured to: display 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, display information on a violation of the coding standard in the selected violating segment.
