    摘要: A structure and associated method to determine an actual resistance value of a calibration resistor within a semiconductor device. The semiconductor device comprises a capacitor, a calibration resistor, and a calibration circuit. A voltage applied to the calibration resistor produces a current flow through the calibration resistor to charge the capacitor. The calibration circuit is adapted to measure an actual time required to charge the capacitor. The calibration circuit is further adapted calculate an actual resistance value of the calibration resistor based on the actual time required to charge the capacitor and a capacitance value of the capacitor.

    摘要: A sub-circuit based extraction method which extracts a multi-finger MOS transistor directly as a sub-circuit is described. By adding three marking layers, the method provides the layout extracted netlist with a complete list of device geometric parameters corresponding to the device properties as presented in the sub-circuit model based schematic netlist. By performing a layout-versus-schematic comparison based on all geometric parameters extracted, the layout checking is performed in a complete and accurate way where each device parameter is checked against the corresponding design schematic. This complete and accurate geometric parameter comparison enhances the confidence level of the layout physical verification.
