Claim:
1. A computer program product for improved modeling of differential circuits, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions being 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 opposite lateral 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 opposite lateral borders, respectively, with the internal input and output differential nodes being connectable; represent respective connections between each of the differential input pair and the internal input node as first and second single, unidirectional, entirely straight and inwardly tapering connection arrows, represent respective connections between the internal output node and each of the differential output pair as third and fourth single, unidirectional, entirely straight and outwardly tapering connection arrows and represent a connection between the internal input and output nodes as a fifth single unidirectional and entirely straight connection arrow; and perform timing calculations with respect to input and output differential nodes.
