1. A cell region comprising:
components representing a first circuit, the components including alpha info conductors and dummy conductors which are substantially collinear correspondingly with reference tracks extending in a first direction,
regarding the first circuit, the alpha info conductors being correspondingly for one or more input signals thereto, or an output signal therefrom, or one or more internal signals internal thereto, and
for a majority of the reference tracks, first ends of corresponding ones of the alpha info conductors or the dummy conductors being aligned relative to the first direction and being proximal to a first side of the cell region;
a first one of the alpha info conductors being on a first one of the reference tracks and being an intra-cell conductor which does not extend beyond the first side nor a second side of the cell region; and
a portion of a first beta info conductor of a second circuit represented by components of a first external cell region, the first beta info conductor being on the first reference track.
