Method and apparatus for automatically generating a multi-terminal net and program storage medium storing a program for executing the method for automatically generating a multi-terminal net

摘要

To automatically generate N-terminal (N is equal to or greater than three) nets according to the present invention, connection data of (N-1) terminals which satisfies a predetermined design rule for a package is input as initial data, and two-terminal nets are generated for a group of wiring start terminals and a group of N-th terminals to which nets are to be generated, in which an intermediate terminal group is ignored. Then, the initial data is combined with the result of the two-terminal generation process to thereby generate provisional nets, and the generated provisional nets are modified so that the design rule for the package is satisfied. In this way, the N-terminal nets are generated automatically.
