Proceedings., 1990 IEEE International Conference on Computer …, 1990•ieeexplore.ieee.orgIn a CMOS double metal gate-array technology, only the M2 layer is available for over-the-
cell routing. A systematic algorithms that intelligently converts global wires into pseudo-pins
and assigns them to each row of cells is presented. The final positions of pseudo-pins
provide a feasible solution for one-layer routine over the cells and minimize wire densities in
the adjacent two-layer routing channels.<>
