Claim:
1. A non-transitory machine-readable storage medium encoded with instructions executable by a processor, the machine-readable storage medium comprising: instructions for generating a first set comprising a first static noise margin curve for a circuit under design and a second static noise margin curve for the circuit, wherein each of the first static noise margin curve and the second static noise margin curve plots a voltage of an input node of the circuit against a corresponding voltage of an output node of the circuit; instructions for adjusting a parameter of a stored model of a cell, wherein the stored model is associated with hardware characterization data and with a second set comprising a third static noise margin curve corresponding to the cell and a fourth static noise margin curve corresponding to the cell, wherein each of the third static noise margin curve and the fourth static noise margin curve plots a voltage of an input node of the cell against a corresponding voltage of an output node of the cell, and wherein the adjusting is performed using a two-dimensional device simulation tool until the second set resembles the first set; and instructions for predicting a condition of the circuit in accordance with the hardware characterization data.
