Abstract

Generating layouts of nets connecting connection terminals of cells in an integrated circuit. Cell layouts of the cells with parameterized locations of the connection terminals, a connection specification of nets specifying electrical connections between the connection terminals, and design rules for the laying out of the nets, are received. A placed layout is generated with the cell layouts placed adjacent to each other in a row. The cell layouts are placed in the row enabling minimization of a selected function. According to the design rules, the nets are laid out as straight interconnects being parallel to a reference straight line using the parameterized locations of the connection terminals in the cell layouts. The laying out includes varying locations of the parameterized locations of the interconnection terminals.
