SPLIT N-WELL CELLS HAVING A MERGED N-WELL DESIGN

Abstract:

An N-well cell stored as a digital representation with a non-transitory computer readable medium. The N-well cell is used within a circuit block of an integrated circuit device. The N-well cell includes a first N-well electrically connected to a first power rail providing a first supply voltage. The first N-well further includes a second N-well electrically connected to the first power rail, and a third N-well electrically connected to a second power rail providing a second supply voltage different from the first supply voltage. The third N-well is positioned between the first N-well and the second N-well. The third N-well includes a first logic sub-block electrically connected to the second power rail, and a second logic sub-block electrically connected to the second power rail.
