Systems and methods for integrated circuit design

摘要

System and methods are provided for integrated circuit design. An initial layout including first circuit units is generated, at least part of the first circuit units obtaining power from a first power supply structure. Second circuit units that obtain power from a second power supply structure are determined, the second circuit units being included in the first circuit units. The second circuit units are grouped. The grouped second circuit units are connected to form one or more grids. The one or more grids are connected to the second power supply structure.

1. A method for generating and transforming an integrated circuit design layout, the method comprising:
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, andhorizontal 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; wherein the generating of the second circuit units, the movingly grouping and the interconnecting are performed by one or more processors.
