Cross bar switch structure for highly congested environments

A method for facilitating fabrication of a semiconductor circuit comprising:

• fabricating a crossbar switch arrangement, the fabricating comprising:
• providing at least two separate groups of multiplexers, an output of which corresponding to an output of the crossbar switch arrangement;
• connecting a set of input lines to data inputs of the at least two separate groups of multiplexers, the input lines extending along a first direction of the semiconductor circuit;
• connecting a set of select lines to select inputs of the at least two separate groups of multiplexers, the select lines extending along a second direction of the semiconductor circuit, wherein the second direction differs from the first direction;
• providing a plurality of select drivers for driving the select lines, the plurality of select drivers being in between one group of multiplexers and another group of multiplexers of the at least two separate groups of multiplexers;
• and
• wherein the at least two separate groups of multiplexers comprise at least one multiplexing circuit for generating a multiplexed signal from signals present at the input lines and at least one primary output driver for generating an output signal from the multiplexed signal.
