Using Bezier Curve to Improve the Accuracy in Integrated Circuit Design Analysis


In this paper, we introduce a method for the application of Bezier curve algorithms to lookup-table-based interpolations, particularly for the use of timing, power, and noise analysis in integrated circuit design. B´zier curves can replace conventional piecewise linear functions for accuracy enhancement. Selecting control points with physical implications and forcing curves to pass through sampled points are critical for achieving the envisioned improvements. This method can be easily applied to the interpolation of splines.
