Abstract
A method of performing physical aware technology mapping in a logic synthesis phase of design of an integrated circuit and a system to perform physical aware technology mapping are described. The method includes subdividing a core area representing a sub-block of the integrated circuit into equal-sized grids. The method also includes determining a location of each of one or more latches in the logic design based on an algorithm, determining a location of each of one or more combinational logic gates in the logic design based on the locations of the one or more latches, and obtaining the technology mapping based on the locations of the one or more latches, one or more input ports, or one or more output ports, the locations of the one or more combinational logic gates, and associated path delays.
