ABSTRACT:
FIELD OF THE INVENTION
This invention relates generally to computer-implemented electronic design automation and more particularly to an improved process for developing software versions of parts used in computer-implemented designs.
BACKGROUND OF THE INVENTION
The ability to rapidly develop software versions of parts for use in computer-implemented product designs is critical in today's environment, where the acceptable time from design to market is continually shrinking. These parts are typically contained in computer aided design (CAD) and computer aided engineering (CAE) parts libraries associated with various software design tools. Part development today, however, is a tedious, error prone and inefficient manual process. Errors in the part data, if left uncorrected, can later cause serious problems in the layout and manufacturing of the designed product.
In accordance with the invention, automation of part development brings about greater consistency, improved quality and higher development efficiency in library data. Library standards for parts are sufficiently detailed to cover both data and process information and are included in the part developers' working process. The working process then becomes a repeatable, divisible process whose steps can be divided among several members of a development team, enabling the part development effort to be distributed across multiple user and part supplier sites.
SUMMARY OF THE INVENTION
A part development system according to the invention includes a process developer environment that executes on a computer for developing part development processes and a part development (or part developer) environment that executes on a computer for developing parts in accordance with such processes, the parts development environment having access to the part development processes and responsive to their selection.
The process developer environment can further include means for providing access to part creation processes, the processes having at least one process command; means for providing access to process commands of a part creation process; and means for constructing a menu of the process commands for use with a data object to develop a part.
The part development environment can further include means for selecting a part development process for developing a part; means for providing access to data objects that can be developed into parts with a selected process; means for selecting an accessible data object; and means responsive to selection of a data object for providing a menu of commands that can be selected for use with the data object to develop a part.
Additional features and advantages of the invention will be made apparent from the following detailed description of an illustrated embodiment which proceeds with reference to the accompanying drawings.
