Abstract
At least one method, apparatus and system disclosed involves a circuit layout for an integrated circuit device comprising a plurality of wider-than-default metal formations for a functional cell. A design for an integrated circuit device is received. The design comprises at least one functional cell. A first pair of wide metal formations are provided. The first pair of wide metal formations comprise a first metal formation and a second metal placed about a first cell boundary of the functional cell for providing additional space for routing, for high-drive routing, and/or for power routing.
Claims20
A method, comprising:
- receiving a design for an integrated circuit device, wherein said design comprises at least one functional cell;
- and
- providing a first pair of wide metal formations comprising a first metal formation and a second metal placed about a first cell boundary of said functional cell for providing at least one of additional space for routing, high-drive routing, and power routing.
A method, comprising:
- receiving a design for an integrated circuit device, wherein said design comprises at least a first functional cell and a second functional cell;
- performing a placement process for placing said first and second functional cells based upon the design;
- and
- providing at a wide M2 metal formation for providing an interconnection between said first and second functional cells, wherein providing said interconnection comprising connecting a first M3 metal formation connected to said M2 metal formation and a portion of said first function cell and a second M3 metal formation connected to said M2 formation and a portion of said second functional cell.
A system, comprising:
- a design unit adapted to provide a design for an integrated circuit device, wherein said design comprises first functional cell and a first pair of wide metal formations comprising a first metal formation and a second metal placed about a first cell boundary of said functional cell for providing at least one of additional space for routing, high-drive routing, and power routing;
- a semiconductor device processing system for fabricating an integrated circuit device based upon said design;
- and
