Definitions
- the presently preferred embodiment of the innovations described herein relate generally to software applications. More specifically, the presently preferred embodiment relates to managing data among embedded components in a product lifecycle management system.
- Embedded software runs on systems that interact with the physical world in real time. These systems, often referred to as embedded systems, are designed to perform specific tasks with optimal efficiency and possess certain unique characteristics.
- a characteristic is that embedded systems should have long life because they often reside in machines that are expected to run continuously for years without errors.
- Another characteristic is that errors in embedded systems are costly. For instance, if a temperature sensor system fails in motors or transformers, they get over heated and fail. Hence, most of the embedded systems are programmed and tested to satisfy zero error tolerance.
- embedded systems should be extremely reliable during operation. Some of the reliability features of embedded systems are: a) safety b) ease of repair, c) ease of shutting down and automatic turn on.
- Embedded systems should not affect other controllers when they fail. Still another characteristic is that embedded systems need to react instantaneously for any input. The embedded system can be outside the reach of humans (down an oil well borehole, or launched into outer space, etc.), so the embedded system must restart itself even if catastrophic data corruption takes place. And still another characteristic of embedded systems, is that they interact with several systems simultaneously and should be designed to concurrently react with many systems in real time with out any problems. Yet another characteristic is they constitute many interdependent components such as hardware, software, firmware and complex networks to exchange messages. This interdependency allows embedded systems to communicate with other systems. For example in a vehicle, a cruise control system communicates to power train to maintain the set speed.
- embedded systems are used to control and/or monitor the operation of machinery and can be found in a variety of product structures executing a variety of applications.
- embedded systems experienced exponential growth due to the ever increasing customer demands with changing product structure requirements.
- An important development in embedded systems is networking. Advances in wireless technology coupled with low cost and compact size integrated chips helped rapid growth of embedded network systems involving volumes of messages.
- the networks enable the embedded systems to communicate with each other and also with the physical world.
- a typical product structure that has an embedded system contains one or more buses that continuously transmit volumes of messages and signals across various components. It is very burdensome to the multitude of developers and designers working on an product structure to track and maintain the embedded system components that go into the product structure while staying with model and other changes that occur throughout the life cycle of a product. Likewise it is difficult to manage the effect a design change has on a network bus or message as they relate to the product structure.
- the present application provides a method for managing embedded component information for a product design in a PLM environment, comprising displaying at least one message object; and associating said at least one message object with a signal object. The method, further comprising auditing said at least one message object. The method, whereby said association satisfies a compatibility rules of signal objects.
- Another advantage of the presently preferred embodiment is to provide a method for managing embedded component information fora product design in a PLM environment, comprising identifying a plurality of message data; associating a transmitting component and a receiving component with at least one of said plurality of message data; and indicating a connection item for at least one of said plurality of message data, wherein said connection item is a carrier of said plurality of said message data.
- the method further comprising auditing said plurality of message data.
- Another advantage of the presently preferred embodiment is to provide a method of providing an embedded system manager for a product design, comprising categorizing a plurality of message data; and generating a compatibility list of a plurality of network devices for said plurality of message data. The method, further comprising auditing said plurality of message data.
- Still another advantage of the presently preferred embodiment is to provide a computer-program product tangibly embodied in a machine readable medium to perform a method for managing embedded component information for a product design in a PLM environment, comprising instructions operable to cause a computer to display at least one message object; and associate said at least one message object with a signal object.
- Yet another advantage of the presently preferred embodiment is to provide a system comprising a windowed environment; and a logical bill of materials application using said windowed environment that includes a hierarchical catalog of a plurality of embedded components having at least one message object; and a system catalog that associates said at least one message object with at least one of a plurality of transmitting components, a plurality of receiving components and a plurality of signal transmitters.
- Yet another advantage of the presently preferred embodiment is to provide a data processing system having at least a processor and accessible memory to implement a method for managing objects within an application, comprising means for displaying at least one message object; and means for associating said at least one message object with a signal object.
- a data processing system having at least a processor and accessible memory to implement a method for managing objects within an application, comprising means for displaying at least one message object; and means for associating said at least one message object with a signal object.
