Abstract: 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.
