  • DETERMINISTIC AND STATISTICAL TIMING MODELING FOR DIFFERENTIAL CIRCUITS
    Publication number: 20170169148
    Abstract: A computer program product for improved modeling of differential circuits is provided. The computer program product includes a computer readable storage medium having program instructions embodied therewith. The program instructions are readable and executable by a processing circuit to cause the processing circuit to represent a configuration of a differential circuit on a defined space with representations of single-ended inputs and outputs disposed as differential input and output pairs along borders of the defined space, respectively, for each differential input and output pair, introduce an internal input or output differential node to feed from or to feed a corresponding differential input or output pair within the borders, respectively, with the internal input and output differential nodes being connectable and perform timing calculations with respect to input and output differential nodes.
    Type: Application
