    摘要: A method of physical design for integrated circuit (IC) chip fabrication, physical design system and program product therefor. A design shape is fragmented into segments for Optical Proximity Correction (OPC) and a harmonic mean of the segments is determined. Electrical intent is determined for the shape and a harmonic mean is determined for the segments. Segments may be moved based on a effect on the harmonic mean from moving the segments, measured using a harmonic mean cost function. Finally segmented shapes are passed to OPC.

    摘要: A methodology for obtaining improved prediction of CA resistance in electronic circuits and, particularly, an improved CA resistance model adapted to capture larger than anticipated “out of spec” regime. In one embodiment, a novel bucketization scheme is implemented that is codified to provide a circuit designer with considerably better design options for handling large CA variability as seen through the design manual. The tools developed for modeling the impact of CA variable resistance phenomena provide developers with a resistance model, such as conventionally known, modified with a new CA model Basis including a novel CA intrinsic resistance model, and, a novel CA layout bucketization model.
