ABSTRACT:
The present invention provides a user of a state diagramming environment with the ability to specify if the user wants to develop a Moore machine or a Mealy machine. To achieve this, a set of predefined requirements is provided that restricts the state diagram semantics to either semantics of a Moore or Mealy machine. When a user provides a state diagram that does not conform to the set of requirements, the state diagram is identified as non-conforming and the user is notified of the non-conformance. The user is given information describing what aspects of the state diagram do not conform, thereby, allowing the user to quickly identify any errors that have been made. As a result of the present invention, the burden placed on the user is reduced and the time spent debugging is minimized.
