Abstract
A technique is disclosed for performing an incremental recompile of an electronic design that has been previous compiled and then changed by a designer. This is accomplished by identifying a 'sub-netlist' within the larger netlist of the changed design. The sub-netlist contains the sphere of influence of the designer's changes to the original design. During incremental recompile, only the sub-netlist is compiled; the remainder of the netlist is left as is from the previous compile. After the sub-netlist is synthesized, it is integrated back into the synthesized netlist from the previous compilation. The newly synthesized netlist for the changed design is mapped to logic cells which are then fit onto a target hardware device.
