Abstract: A method for timing analysis includes receiving a physical design of an electric circuit, selecting a timing path within the electric circuit, and determining that the selected timing path includes a first logic cell implemented with a first type of transistor and a second logic cell implemented with a second type of transistor. The method further includes running a set of process corners with the first type of transistor at a given corner and the second type of transistor at a condition other than the given corner. The first type of transistor has a delay that is based on process correlation with the second type of transistor. The method also includes determining whether a timing requirement is met or not met for the selected timing path, and then reporting whether the timing requirement is met or not met.

Abstract: A system comprising an ambient energy source, a power supply, and a power storage device. The ambient energy source is coupled to a first terminal end of an inductor. The power supply is also coupled to the first terminal end of the inductor. The power storage device is coupled to a second terminal end of the inductor. The ambient energy source provides power through the inductor in a first direction to the power storage device. The power storage device provides power through the inductor to the power supply in a second direction opposite the first direction.
