Abstract
An integrated circuit has integrated circuit cells drawn from a library. The cells are rectangular with input lines extending from both sides of the cell to a logic element on the cell and outputs taken from the logic element to both sides of the cell. Input and output lines terminate at connection points. Short linear lengths of conductors selectively interconnect the connection points across the boundary between adjacent cells. The arrangement permits on-cell series and parallel connection of cells.
