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

A system for specifying system level constraints for connecting an interface between first and second fabrics of an electronic device, the interface having a net to be connected from one connector in the first fabric to a second connector in the second fabric, the connectors being defined by their respective location within the corresponding one of the first and second fabrics, the system comprising:

• a first descriptor that specifies one or more first condition relating to a placement of the interface within one of the first and second fabrics;
• a second descriptor that specifies one or more second condition relating to a connection of the net in the interface between the first and second fabrics;
• and
• one or more processors configured to execute an equation generator module that generates one or more first equation expressing the first condition as a function of the location of the connectors within the one of the first and second fabrics, one or more second equation expressing the second condition as a function of the location of connectors within the one of the first and second fabrics and one or more third equation expressing an optimality criterion for the interface.

A non-transitory computer readable medium storing a set of instructions which, when executed by a computer processing system, causes the computer processing system to process input data representing locations of connectors of an interface of an electronic device to specify system level constraints for connecting a net of the interface from one connector in the first fabric to a second connector in the second fabric, the set of instructions comprising:

• a first descriptor module that cause the computer system to input one or more first condition relating to a placement of the interface within one of the first and second fabrics;
• a second descriptor module that causes the computer system to input one or more second condition relating to a connection of the net in the interface between the first and second fabrics;
• an equation generator module that causes the computer system to generate one or more first equation expressing the first condition as a function of the location of the connectors within the one of the first and second fabrics, one or more second equation expressing the second condition as a function of the location of connectors within the one of the first and second fabrics and one or more third equation expressing an optimality criterion for the interface;
• and
• a data exchanger module that outputs the one or more first equation, the one or more second equation and the one or more third equation to a data file.
