Abstract
Systems and techniques for optimizing an integrated circuit (IC) design are described. A logic-function identifier can be determined based on a fan-in combinational-logic-cone, wherein the logic-function identifier corresponds to a logic function that is implemented by the fan-in combinational-logic-cone. An arrival-time-pattern identifier can be determined based on a set of arrival times at inputs of the fan-in combinational-logic-cone. An optimized combinational-logic-cone can be obtained by performing, in addition to optionally other operations, a database lookup by using the logic-function identifier and the arrival-time-pattern identifier. Next, the fan-in combinational-logic-cone can be replaced with the optimized combinational-logic-cone in the IC design.
