7.4 Nwell --------- This drawn layer is to define the Nwell for both 3.3V & 5V/6V PMOS transistors. For Nwell as a resistor it can only be used outside DNWELL, as by default all Nwell inside DNWELL will be shorted together through DNWELL. .. csv-table:: NWELL RULES :file: tables_clear/13_Nwell31.csv :widths: 200, 700, 100, 100 :align: center .. image:: images/nwell.png :width: 800 :align: center :alt: Nwell .. note:: \* :ref:`Rules not coded`
