ABSTRACT:
A CAD apparatus for designing wires for an LSI or a printed circuit board is improved in that it can detect and determine a wire which is very probably influenced by crosstalk noise accurately in a short time and allows to make it clear how to modify wires. The CAD apparatus comprises a CAD execution section for designing wires, a display section for displaying a wire condition designed by the CAD execution section, and a display control section for controlling the displaying condition of the display section. The display control section controls the display section to display wire patterns of wires on the LSI or the printed circuit board obtained by designing of wires by the CAD execution section as well as the signal propagation directions of the individual wires.
