Abstract:
A method for creating a characterized digital library to be used for circuit design comprising:selecting a sub-window with an upper boundary and a lower boundary, wherein each of the upper boundary and the lower boundary exists within a window constrained by a first boundary and a second boundary wherein one of either the first boundary or the second boundary is guaranteed to produce a successful simulation and the other of the one of either the first boundary or the second boundary is guaranteed to produce a failed simulation; generating an upper simulated value for the upper boundary and a lower simulated value for the lower boundary; when only one of either the upper simulated value and the lower simulated value produces success, performing a binary subdivision to select a simulated characterization value within the window that satisfies a predefined resolution; and performing a failure recovery when both the upper simulated value and the lower simulated value produce one of either success or failure.
