Abstract
A system and method for constructing a clock tree based on replica stages is described. The system and method may comprise determining a size of an input buffer for driving a load capacitance of the output buffer based on a fanout, determining a wire width and a wire length based on the size of the output buffer, the fanout and a replica stage mathematical model, and connecting the output buffer and the corresponding input buffer to a conductor routed on one or more predetermined metal layers and having the wire length and the wire width. The conductor is placed within ground shields having a fixed width.
