Fecha de publicación: 03/01/2023 Fuente: WIPO (eseential oils OR extracts) A computer/software tool for electronic design automation (EDA) extracts parasitics from a post-layout netlist file for an integrated circuit (IC) design and uses these parasitics to model circuit behavior specifically to assess matching of reciprocal objects of a matched circuit. The computer/software tool generates a visual display based on the calculated design characteristics; for example, in one embodiment, asymmetry can be color-coded to permit a designer to visualize sources of matching problems base on mismatched parasitics. In other embodiments, the parasitics, structural elements and/or results can be filtered and/or processed, e.g., so as to provide EDA driven assistance to reduce excessive sensitivity to certain parasitics, and to minimize net and device systematic (layout-based) mismatch.
