Abstract:
A method of gridded glyph geometric objects (L3GO) integrated circuit (IC) design, wherein at least one inter-level connect in a L3GO circuit design is represented as a point matrix glyph (PMG) on a L3GO grid. Each PMG connects a pair of conductors on the next adjacent (above and below) layer and includes an array (one or two dimensional) of point glyphs contained within a cage. The point glyphs may have uniform size and may be on minimum pitch. Each PMG may also include a flange on the above and below layer. A default flange insures adequate coverage of cut shapes represented by the point glyphs.
