Terminal layer setting method for semiconductor circuit having a plurality of circuit layers, storage media storing terminal layer setting program, storage media storing a wiring terminal extension processing program and terminal extending component used for setting of the terminal layer

摘要

A terminal layer setting method according to the present invention is a method for a computer setting up a terminal layer of a semiconductor circuit having a plurality of wiring layers, comprises the steps of obtaining various kinds of information such as placement information relating to a plurality of cells or macros constituting the semiconductor circuit and being mounted onto a circuit board from a storage unit of the computer; comparing between a driving capacity of a subject cell or macro, which is contained in the obtained information, and a resistance of wiring for connecting the subject cell or macro with a cell or macro at a connecting destination; and setting up a terminal layer which is a wiring layer at an extending destination of a wiring terminal for the subject cell or macro based on the comparison result.
