  "message": "Corrected the parasitic capacitance tables in the magic techfile to\naccount for deep nwell to substrate, and shielding of fringing\ncapacitance from poly and all metal layers to substrate by nwell\nand pwell, which was missing.  The missing shielding caused nodes\nto have coupling capacitance to substrate even when they were\nshielded from substrate (the plate area capacitance was calculated\ncorrectly, but the fringing capacitance can be large).\n",
