20110184706 | OPTIMIZATION PROCESSING METHOD AND APPARATUS - A first model expression having a first order and representing a relationship between evaluation indicators and the design parameters and a second model expression having a second order higher than the first order and representing a relationship between them are generated. Then, according to a quantifier elimination method, values of said design parameters, which realize an optimum solution of the first model expression, are calculated. And, a design parameter whose value is identical to an upper limit value or a lower limit value is identified, and the second model expression is transformed by substituting the upper limit value or the lower limit value, as a value of the identified design parameter, for the second model expression. Finally, according to the quantifier elimination method, values of the design parameters in the transformed second model expression, which realize an optimum solution of the transformed second model expression, is calculated. | 07-28-2011 |

20110295573 | MODEL EXPRESSION GENERATION METHOD AND APPARATUS - When model expressions of objective functions are generated at vertexes of a quadrilateral on a plane concerning P and N channels of transistors in SRAM, the initial number of times of simulation is allocated to each objective function at each designated vertex according to weight values set based on relationships presumed among the objective functions at each designated vertex. For each objective function at each designated vertex, first simulation is executed the allocated number of times. Furthermore, a model expression is generated from the first simulation result, and an evaluation indicator of an approximation accuracy of the model expression is calculated. Then, for each model expression, it is determined whether the corresponding model expression has influence on the yield, and based on the evaluation indicator of the corresponding model expression and presence or absence of the influence, it is determined whether additional simulation is required for the corresponding objective function. | 12-01-2011 |
