IBM's high-performance microprocessor designs leverage internally developed electronic design automation tools to create high-frequency, power efficient, and robust microprocessors. This paper describes some of the tools employed in the custom circuit design methodology in IBM. The tools described include a transistor-level block-based static timer, a static noise analysis methodology, and a transistor width tuner that optimizes performance and area. We also describe the application of electrical rule checking used to enforce consistent design practices. Finally, we discuss a macro extraction tool that determines parasitic resistance and capacitance of interconnect from a layout
