1. A method comprising: removing a code segment from a hardware description language design to create a modified hardware description language design, the code segment representing at least one time sensitive path in the hardware description language design; creating a delta list of differences between the modified hardware description language design and a physical hardware representation that is logically equivalent to the hardware description language design; extracting a portion of the physical hardware representation that corresponds to the at least one time sensitive path based, at least in part, on the delta list; and creating a structured hardware description language design of the at least one time sensitive path using the extracted portion of the physical hardware representation, wherein the structured hardware description language design comprises structural information of the extracted portion of the physical hardware representation.
