摘要： A method for computing a Miller-factor compensated for peak noise is provided. The method includes mapping at least two delays as a function of at least two Miller-factors; determining an equation of the function; computing a peak noise; computing a peak delay resulting from the peak noise; and computing the compensated Miller-factor based on the equation and the peak delay. The function can be either a linear function or a non-linear function.

摘要： A system and method for estimating propagation noise that is induced by a non-zero noise glitch at the input of the driver circuit. Such propagation noise is a function of both the input noise glitch and the driver output effective capacitive load, which is typically part of the total wiring capacitance due to resistive shielding in deep sub-micron interconnects. The noise-driven effective capacitance solution provided herein also estimates the propagation noise induced by a non-zero noise glitch at the input of the driving gate. Gate propagation noise rules describing a relationship between the output noise properties and the input noise properties and the output loading capacitance are used within the noise-driven effective capacitance process to determine the linear Thevenin model of the driving gate. The linearized Thevenin driver model is then employed to analyze both the propagation noise and the combined coupling and propagation noise typically seen in global signal nets.
