Abstract
A method for determining routes of wiring nets by utilizing artificial neural networks includes the steps of dividing the wired area into smaller areas, representing each boundary through which one wiring net passes is capable of passing as an artificial neuron, changing an output value of the artificial neuron according to whether or not the wiring net actually passes through the boundary, composing an artificial neural network in which the interaction between the artificial neurons is taken into consideration according to one or more prescribed conditions restricting each route of the wiring nets while changing the output values of the artificial neurons, converging the output values of all artificial neurons, and determining the routes of all wiring nets by judging whether or not each wiring net passes through a boundary according to the converged output values of the artificial neurons.
