Crosstalk cancellation circuit, interconnection module, interconnection method of automatic interconnection apparatus, and integrated circuit

An interconnection module in an integrated circuit, comprising:

• M (M is a natural number) number of inverters;
• input lines of said M number of inverters;
• output lines of said M number inverters;
• and
• L number of signal lines, and
• wherein said input lines, said output lines, and said signal lines are parallel or substantially parallel to each other, and wherein said inverters, input lines, and output lines of the related inverters and said signal lines are alternately arranged (note, where M=1, L=M or L=M+1 and where M≧2, L=M, L=M+1, or L=M−1).

A method of interconnection of an automatic interconnection apparatus for laying out interconnections in an integrated circuit, comprising the steps of:

• a first step of arranging a plurality of interconnections parallel or substantially parallel;
• and
• a second step of inserting the same number of inverters at said plurality of interconnections, and
• wherein said second step having a third step of inserting each inverter at a location where crosstalk noise due to a parasitic capacity of the adjoining interconnections is canceled out or substantially canceled out on the related adjoining interconnections.

An integrated circuit comprising

• a crosstalk cancellation circuit for suppressing crosstalk noise of interconnections in an integrated circuit, and
• wherein said crosstalk cancellation circuit comprises
• N (N is an even number of 2 or more) number of first inverters,
• a first interconnection for connecting the N number of first inverters in series, N number of second inverters, and
• a second interconnection for connecting said N number of second inverters in series, and
• Wherein said first and second interconnections are arranged adjacent in parallel or substantially parallel to each other,
• wherein at least one first inverters among said N number of first inverters is arranged at a location where crosstalk noise due to a parasitic capacity between said first and second interconnections is canceled out or substantially canceled out on said second interconnection, and
• wherein at least one second inverter among said N number of second inverters is arranged at a location where crosstalk noise due to a parasitic capacity between said first and second interconnections is canceled out or substantially canceled out on said first interconnection.
