Abstract: A method for designing an integrated circuit is disclosed. The method generally comprises the steps of (A) splitting a design layout of the integrated circuit into a plurality of tiles, (B) adding a plurality of tie-to cells to the design layout, wherein at least one of the tie-to cells generating a tie-to signal at a particular logical level is added into each of the tiles having at least one gate with an input fixed to the particular logical level and (C) routing the tie-to signal to each of the inputs within each of the tiles.

Abstract: A method for implementing a circuit design is disclosed. The method generally includes the steps of identifying, replacing and routing. The first step may identify a first cell of the circuit design having (i) a function and (ii) an input pin connectable to one of a first power rail and a second power rail having a different voltage than the first power rail. The second step may replace the first cell with a second cell having (i) the function, (ii) the input pin and (iii) at least one blocking characteristic that reserves (a) a first route completely within a particular conductive layer of the cell between the input pin and the first power rail and (b) a second route completely within the particular conductive layer between the input pin and the second power rail. The third step may route the circuit design incorporating the second cell such that the input pin is connected to one of (i) the first power rail using the first route and (ii) the second power rail using the second route.
