An integrated circuit (IC) design, method and program product for reducing
IC design power consumption. The IC is organized in circuit rows. Circuit
rows may include a low voltage island powered by a low voltage
(V.sub.ddl) supply and a high voltage island powered by a high voltage
(V.sub.ddh) supply. Circuit elements including cells, latches and macros
are placed with high or low voltage islands to minimize IC power while
maintaining overall performance. Level converters may be placed with high
voltage circuit elements.
