Latest Patents
Li-Fu Chang's latest patents include advancements in timing, noise, and power analysis of integrated circuits. These Design for Manufacturing (DFM) systems incorporate manufacturing variations in the analysis of integrated circuits. They calculate predicted manufacturing variations on the shapes of interconnects and devices of the drawn layout of a circuit design. The shape variation on interconnects is converted to variations in resistor-capacitor (RC) parasitics. Additionally, the shape variation on devices is converted to variations in device parameters. The variation in device parameters and wire parasitics is then translated into changes in timing performance, signal integrity, and power consumption. This is achieved by determining the impact of device parameter and wire parasitic variations on the behavior of each instance of a standard cell. The results from these analyses are integrated back into the design flow as incremental delay files for timing, noise failures, and buffer insertion/driver resizing commands for noise, as well as leakage power hotspots and cell substitution commands for power consumption.
