20090138417 | Parameter Adjustment Device - Efficient and high-accuracy parameter adjustment is performed by applying a genetic algorithm to a parameter adjustment such as a physical model of a transistor and so on. A parameter adjusting device includes a device generating new parameter genes by an initial population generating device and a special crossover processing by a Latin hyper square method. Also, a normalization device is provided for applying to parameters which are real numbers. Moreover, for example, to exactly meet a specific property of the transistor (MOSFET), an evaluation device which evaluates a parameter in consideration of a log scale, is provided. According to the above-mentioned structure, the genetic algorithm can be applied to the parameter adjustment with a large number of parameters such as the physical model of the transistor and so on, so that a parameter group can be determined with a high degree of accuracy within a short time. | 05-28-2009 |
