Disclosed is an improved method, system, and computer program product to perform automated generation and/or modification of control scripts for EDA tools. A script generator/modifier mechanism is used to access an optimization database to identify potential content of the control script. This potential content is then analyzed to identify the appropriate content to insert into the control script, to accomplish the intended goal of the user in operating the EDA tool. The script generator/modifier mechanism may itself be implemented in a script format.

Method and system for automated script generation for EDA tools

A method of optimizing clock-gated circuitry in an integrated circuit (IC) design is provided. A plurality of signals which feed into enable inputs of a plurality of clock gates is determined, where the clock gates gate a plurality of sequential elements in the IC design. Combinational logic which is shared among the plurality of signals is identified. The clock-gated circuitry is transformed into multiple levels of clock-gating circuitry based on the shared combinational logic.

Multi-level clock gating circuitry transformation

A power optimization method of deriving gated circuitry in a synthesized netlist of an integrated circuit (IC) design is provided. A block in the synthesized netlist is identified as an idle candidate block. Sub-blocks on the chip are clustered into a cluster. For the cluster, a clock gating structure optimized for power savings is determined, based on the idle candidate block. One or more inflexible clock gates are inserted in the netlist according to the clock gate structure.
