7.3 Lvpwell ----------- This drawn layer is defined for 3.3V and 5V/6V NMOS body . If this layer is used without DNWELL (outside DNWELL), the body of all those transistors will by default be connected to P-substrate potential. If LVPWELL is designed as a resistor, it is not allowed to be placed outside DNWELL. **(A) LVPWELL Inside DNWELL** .. csv-table:: LVPWELL RULES (Inside DNWELL) :file: tables_clear/12_LVPWELL29_1.csv :widths: 200, 700, 100, 100 :align: center .. note:: \* :ref:`Rules not coded` \*\* This note is a layout guide for customer and this rule can be detected by ERC, not by DRC .. image:: images/lvpwell1.png :width: 800 :align: center :alt: LVPWELL **(B) LVPWELL Outside DNWELL** .. csv-table:: LVPWELL RULES (Outside DNWELL) :file: tables_clear/12_LVPWELL29_2.csv :widths: 200, 700 , 100 :align: center .. image:: images/lvpwell2.png :width: 800 :align: center :alt: LVPWELL
