  • Verification method with the implementation of well voltage pseudo diodes
    Patent number: 7895554
    Abstract: A method of verifying consistency between a circuit schematic and a corresponding integrated circuit layout is disclosed. The method includes identifying a voltage condition associated with a portion of the circuit schematic, and assigning a pseudo diode to the portion of the circuit schematic that is uniquely associated with the identified voltage condition. The method further includes coding a pseudo layer associated with an integrated circuit layout of the circuit schematic in accordance with content of the assigned pseudo diode, and verifying consistency between the circuit schematic and the corresponding integrated circuit layout by extracting the pseudo layer from the integrated circuit layout and comparing information of the pseudo layer to the assigned pseudo diode in the circuit schematic.
