If a transistor has width W that is larger than the folding threshold F, then (W div F) transistors of width F are generated. If (W mod F) is smaller than the minimum width, then the extra width is added to the last of the (W div F) transistors; | If a transistor has width W that is larger than the folding threshold F, then (W div F) transistors of width F are generated.
