Abstract: Geometry for component packages are generated by reading from computer memory a package data file that provides physical dimension information for a component package; determining which of a number of rulesets applies to the package data file; and generating a geometry for the component package by applying rules of an applicable ruleset to the package data file. The method may further include determining which of a number of site parameters and/or board technology parameters applies to the package data file; and generating a geometry for the component package by applying rules of an applicable ruleset to the applicable site and/or board technology parameters.

Abstract: A part development system implemented on a computer for developing software versions of parts for use in computer-generated designs, such as electrical circuits. The system includes a process developer environment for developing part development processes and a parts developer environment for developing parts in accordance with such processes. In a preferred embodiment, the two environments are implemented as computer programs with graphical interfaces to enable process developers to easily construct part development processes and parts developers to easily develop parts using the processes. The part development processes capture the library and part specifications required for acceptable parts, thus minimizing errors in part creation and time required for test.
