Abstract
Methods, apparatus and computer program products for modeling integrated circuits having dense devices therein that experience linewidth (e.g., gate electrodes) reductions during fabrication are provided. For dense devices having electrical paths therein and first and second gate electrodes that overlie the electrical path, operations include determining an electrical gate length of the first gate electrode by evaluating a change in current through the electrical path relative to a change in gate length of the second gate electrode. The operation to determine the electrical gate length of the first gate electrode includes evaluating a change in simulated drain-to-source current through the electrical path relative to a change in the electrical gate length of the second gate electrode.
