Systems and methods for integrated circuit design

A system for generating and transforming an integrated circuit design layout, the system comprising:

• one or more data processors;
• and
• a non-transitory computer-readable storage medium encoded with instructions for commanding the one or more data processors to execute operations including:
• generating an initial layout including first circuit units configured to obtain power from a first power supply structure;
• generating second circuit units configured to obtain power from a second power supply structure, the second circuit units being included among the first circuit units;
• movingly grouping the second circuit units spatially together into a matrix configuration that comprises at least two horizontally-extending rows of the second circuit units and at least two horizontally-extending columns of the second circuit units, and wherein the second circuit units are located directly under and vertically below a horizontally-extending conductive layer of the second power supply structure;
• interconnecting the grouped second circuit units with a grid that includes
• for each of the second circuit units, a vertical conductive line extending vertically from the respective second circuit unit, and
• horizontal conductive lines that interconnect the vertical conductive lines;
• and
• connecting the grid to the second power supply structure with cross-layer connections, in which each of the cross-layer connections extends vertically upward from a respective one of the second circuit units to the conductive layer.

An integrated circuit comprising:

• the second circuit units are located directly under and vertically below a horizontally-extending conductive layer of the second power supply structure;
• the second circuit units are interconnected with a grid that includes
• for each of the second circuit units, a vertical conductive line extending vertically from the respective second circuit unit, and
• horizontal conductive lines that interconnect the vertical conductive lines, and
• the grid is connected to the second power supply structure by cross-layer connections, in which each of the cross-layer connections extends vertically upward from a respective one of the second circuit units to the conductive layer.
