1. An integrated circuit (“

  • IC”

    ) having a design based on a layout, said layout defined by using a wiring model that allows at least a particular wiring layer of the IC to have at least two preferred interconnect directions in at least a region of the particular wiring layer, wherein in no part of the region on the particular layer are routes in either of the two preferred interconnect directions assessed a non-preferred direction routing penalty that results in one of the two preferred interconnect directions being more preferable than the other preferred interconnect direction.
