20120123917 | SYSTEM AND METHOD FOR VARIABLE TIME-BASED LICENSING - A system and method for variable time-based licensing is provided, which includes a chips cache which stores activated chips and a chips pool which stores inactive chips. In this context “chips” can be considered a currency which can be traded to use software tools for a period of time associated with each chip. The system further includes a chips accounting manager, operable to receive license requests for software tools and to determine whether to grant the license request; and a license manager which tracks active chips and manages activated chip check-in and checkout. When the chips accounting manager receives a license request for a software tool the chips accounting manager determines whether the chips cache includes sufficient chips to access the software tool. If there are insufficient chips, the chips accounting manager checks whether inactive chips in the chip pool can be activated and added to the chips cache. If there are sufficient chips, the chips accounting manager notifies the license manager to check out the sufficient chips from the chips cache and grant access to the software tool. | 05-17-2012 |

The method combines the one or more desired characteristics with other preset characteristics of the transformer or the integrated circuit. A first model of the transformer is defined with typical load impedances and simulated having the combined characteristics to determine performance. Results of the simulation are processed to calculate performance with the load impedances specified by the user. The results are further processed to obtain a mathematical model that includes tuning capacitors. The first and subsequent models are modified by drawing on a rule-set of expert knowledge relating to general dependency of at least one design criterion, such as a physical, geometrical or performance characteristic, with another design criterion. | 04-09-2015 |
