Abstract

A method for assigning interconnection resources to input/output connection points on differential current switch logic elements which need to use the resources, but which introduce an order dependency to the assignment problem, due to restrictions unique to differential current logic. The input/output connection points are paired first as are the interconnection resources. Pairing removes the order dependency. An assignment is then made through the use of an optimizing linear assignment algorithm suitable for single input/output connection point to single interconnection resource assignments. Preferably, a cost matrix is generated to determine the optimum assignment by minimizing the total assignment cost. The paired assignments are then broken apart to assign each individual member of the point pair to an individual member of the assigned resource pair. The final assignment of the individual pair members is compared to legality constraints, the violation of which may have been masked in the calculation of assignment costs of the pairs.
