Automatically wiring method for integrated circuit

Abstract

Abstract PURPOSE:To obtain an excellent wiring result by automatically updating a parameter value according to an evaluation result obtained by evaluating a wiring result obtained at each wiring. CONSTITUTION:When an integrated circuit is automatically wired by controlling the wiring of the circuit by a parameter, the parameter has a continuous parameter value continuously varying within a predetermined range, a wiring decision is executed according to a plurality of discrete parameter values discretely extracted from the parameter values, the wiring decision result in the executed decision is evaluated according to an evaluation reference, the evaluation result of the continuous parameter value is obtained in response to the obtained result, the result of the continuous value is summed to be updated to an evaluation result corresponding to the already obtained continuous value, and the parameter value of next wiring decision is decided by a probability so that the value for satisfying a predetermined reference of the summed and updated result is more easily selected. Thus, the value is automatically and optimally regulated to obtain an excellent wiring result.
