Abstract
A wiring editing method for a semiconductor package of this invention includes the steps of assuming virtual circular arcs R to R in consideration of a clearance around a predetermined via in a designated area on a virtual plane, drawing a regular polygon circumscribing each of the virtual circular arcs R to R drawing a tangent from a via crossed by one of the virtual circular arcs R to R to the crossing virtual circular arc and connecting to the regular polygon circumscribing the crossing virtual circular arc to thereby form a wiring pattern and moving or omitting redundant line segments forming the regular polygon in the wiring pattern to change a wiring route when an offset occurs in the wiring pattern passing between the vias inside the designated area.
