ABSTRACT:
A system for reducing the signal delay skew is disclosed, according to a variety of embodiments. One illustrative embodiment of the present disclosure is directed to a method. According to one illustrative embodiment, the method includes receiving an initial netlist comprising components and connection paths among the components. The method further includes identifying one or more skew-influencing features in a first connection path in the initial netlist that lack corresponding skew-influencing features in a second connection path in the initial netlist. The method also includes generating a skew-corrected netlist wherein the second connection path includes one or more added skew-influencing features corresponding to those of the first connection path. The method further includes outputting the skew-corrected netlist.
