Diagnosis of a defect on a nonintersection electrode.
benign defects include all the defects in the unused entrance electrodes for
the well and all the electrodes between the bottom entrance electrodes and
the left/right routing pathways if all the wells are loaded from the right/left
side. For these benign defects, no defect tolerance is needed.
The second category of defects occurs on the electrodes used by the
well-loading algorithm on the electrode rows but not on the routing path-
ways. These defects are referred to as loading pathway defects, as shown in
Figure 6.15. These defects can be bypassed by simply changing the side from
which the well is loaded.
The third category includes all the defects on the routing pathways. There-
fore, we refer to them as routing pathway defects. Unlike loading pathway
