A method of connecting an interface to a fabric of an electronic device, the interface having a plurality of nets to be connected to corresponding connectors in the fabric includes associating with each of the connectors in the fabric a first variable indicating that the connector belongs to the interface; associating with each of the connectors in the fabric a second variable indicating a number of higher numbered adjacent connectors for the connector in the interface; connecting each of the nets in the interface to a corresponding one of the connectors in the fabric such that the second variable has a non-zero value at exactly one of the corresponding connectors in the interface.

Method and system for optimally connecting interfaces across multiple fabrics

A method of specifying system level constraints for connecting an interface of an electronic device between first and second fabrics includes specifying one or more first condition relating to a placement of the interface, specifying one or more second condition relating to a connection of a net in the interface between the first and second fabrics, generating one or more first equation expressing the first condition as a function of the location of the connectors, generating one or more second equation expressing the second condition as a function of the location of connectors, generating one or more third equation expressing an optimality criterion for the interface, and outputting the one or more first equation, the one or more second equation and the one or more third equation to a data file in a computer readable format.

Method and system for specifying system level constraints in a cross-fabric design environment

A system for connecting an interface of an electronic device between first and second fabrics includes a constraint generator that associates first and second conditions with the interface, a first equation solver that solves one or more first equation to select a first plurality of connectors in the first fabric and a second plurality of connectors in the second fabric that satisfy the first condition based on an optimality criterion for the interface; and a second equation solver that solves one or more second equation to select one of the first plurality of connectors in the fabric and one of the second plurality of connectors in the second fabric that satisfy the second condition based on the optimality criterion for the interface.
