Abstract: Systems and techniques for optimizing an integrated circuit (IC) design are described. Some embodiments can transform a circuit design into a logically-equivalent circuit design by: (1) creating a Wire-Length-Area Model (WLAM) for a portion of a first circuit design, (2) creating a second circuit design by replacing the portion of the first circuit design by the WLAM, (3) placing and routing the second circuit design to obtain a placed-and-routed second circuit design, and (4) creating a third circuit design that is logically-equivalent to the first circuit design based on the placed-and-routed second circuit design.

Abstract: A method and system are provided for generating a logic network using a hardware independent description means. A logic circuit synthesizer, in response to a user description specifying only signals and the circumstances under which the signals are produced, generates a logic network that generates the signals specified in the user description, e.g., a net list of logic elements, such as logic gates, high impedance drivers, level sensitive latches and edge sensitive flip-flops along with the interconnections of the logic elements. In one embodiment, the logic circuit synthesizer includes a preprocessor means and a logic circuit generator means. The preprocessor means, in response to the user description, converts signals and conditions in the user description into a structure having nodes interconnected by edges. The edges include an edge condition under which the edge is traversed.
