Abstract: A method, system and program product are disclosed for statistical modeling an integrated circuit that provides information about partial correlations between model parameters. The invention determines a variance-covariance matrix for data to be modeled; conducts principal component analysis on the variance-covariance matrix; and creates a statistical model with an independent distribution for each principal component, allowing calculation of each individual model parameter as a weighted sum by a circuit simulator. The statistical model provides information about how well individual transistors will track one another based on layout similarity. This allows the designer to quantify and take advantage of design practices that make all transistors similar, for example, by orienting all gates in the same direction. A method, system and program product for simulating a circuit using the statistical model are also included.
