  • Patent number: 8386976
    Abstract: A method for producing a layout of a device in an integrated circuit before actually fabricated is provided. The method includes inputting at least one fixed parameter for the device for fabrication. And then, a first part of a set of variable parameters of a layout of the device is input. The complete set of the variable parameters is generated. It is checked whether or not the layout with the parameters is satisfying a requirement, wherein an end step is reached if the layout is accepted by the requirement, and a new part of the set of variable parameters as the first part being looping in the foregoing steps if the layout is not accepted by the requirement.

  • Publication number: 20080200132
    Abstract: A method for producing an IC layout with radio frequency devices is provided. The method has following steps. Type information of at least one RF device is inputted, and at least one RF parameter corresponding to the RF device is inputted as well. A frequency response result is then generated based on the type information and the RF parameter. When the frequency response result meets the required specification, an IC layout process is performed based on the frequency response result. However, when the frequency response result doesn't meet the required specification, another RE parameter is inputted again to produce new frequency response result.
