In one embodiment, a design methodology is described in which a functional description of each macro may be synthesized along with the other logic in a block. The resulting circuitry, including synthesized circuitry corresponding to each macro, may be placed within an area designated for the integrated circuit. The result may be analyzed, determining a location for the macro based on the location of the corresponding synthesized circuitry. For example, the geometric center of the synthesized circuitry may be located, and the geometric center of the custom circuitry associated with the macro may be placed at the same point as the geometric center of the synthesized circuitry. Because the macros are not placed in advance, the location of the macro may be controlled by other factors such as timing, space, wiring congestion, etc. |
