A method, system, and computer program product are disclosed for performing RC extraction. The present approach can consider multiple types of manufacturing processes, and allows location-based prediction data to be used in the context of net-based analysis. RC extraction can be more accurately performed based upon net-specific top and bottom adjustments to thickness prediction that are location-based. The net-based prediction data can be used for other purposes as well, such as to perform electrical hotspot analysis, to visually display physical properties of the nets, or allow queries for other data analysis purposes.

Method and system performing RC extraction

A method, system, and computer program product are disclosed for performing RC extraction from the perspective of the block level. A translation mechanism is employed to convert from a full-chip design domain to a block-level design domain. This allows model-based prediction results to be used in the early design implementation flow when parasitic RC and timing extractions are performed, where the model-based prediction results relate to predictions of manufacturing variations such as thickness and topography.
