Abstract:
A design aiding apparatus for aiding placement of any of components, conductors and vias in a multilayer circuit board which includes at least one signal layer and at least one layer that is one of a power layer and a ground layer, the design aiding apparatus comprising:routing path area generating means for generating a routing path area on at least one signal layer or at least one layer that is one of a power layer and a ground layer, the routing path area partly including one of a signal line routed on a signal layer and a feedback path of a current which flows over a signal line routed on a signal layer; and position calculating means for calculating, based on the generated routing path area, one of a position at which any of components, conductors and vias is to be placed and a position at which any of components, conductors and vias is prohibited to be placed, to minimize an area enclosed by a loop formed by a current which flows over a signal line and a feedback path corresponding to the signal line.
