Abstract
A method for designing a circuit element of an integrated circuit (IC) includes receiving one or more desired characteristics of the circuit element from user input and iteratively determining a design solution through one or more simulations and modifications using a rule-set. The one or more desired characteristics are combined with other preset characteristics of the circuit element or the IC. A first model of the circuit element is defined and simulated to calculate performance. 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.
