Abstract: The invention includes computer instructions that operate to generate a failure indication upon encountering a failure during an operation performed for a user design. The instructions further operate to automatically facilitate a user in determining a solution for the failure. As a result, the invention provides improved error reporting and recovery.

Abstract: The invention comprises a method and device for dynamic message delivery based upon the identification of an originating caller. Specifically, the originating caller for an incoming call is identified and compared to a list of callers, where each caller within the list of callers is associated with one of a plurality of dispositions, the dispositions including accept, reject and forwarding of an incoming call. The incoming call is routed based upon the disposition associated with the identified originating caller. In the case of a subscriber utilizing a dial-up internet account, a message is sent to the subscriber via the internet connection alerting the subscriber that an incoming call is present and offering the subscriber various disposition options.

Abstract: A method and apparatus for processing and representing error messages within a computer-aided design environment is described. The present invention allows error/warning information to be stored in a central storage location by the function in which the error/warning causing fault occurs. The function then returns a result indicating that the function did not perform as expected. The calling function does not add an error/warning message of its own when returning, if necessary, to another calling function. Thus, only a single warning/error message can be stored and used for reporting the fault that caused the error/warning. In one embodiment, a hierarchical graphical error/warning log provides varying levels of error/warning information in response to user input.
