Abstract
In a semiconductor integrated circuit device including a plurality of semiconductor devices formed on a substrate, the principal plane of the substrate is partitioned into a plurality of device regions and into a plurality of routing regions each crossing a boundary between the plural device regions. A device group including one or more semiconductor devices among the plural semiconductor devices and a local interconnect for connecting the semiconductor devices included in the device group are disposed within the plural device regions. A global routing for connecting the device groups to each other is disposed within each of the plural routing regions.
Claims6
A semiconductor integrated circuit device comprising a plurality of semiconductor devices formed on a substrate,
- wherein a principal plane of said substrate is partitioned into a plurality of two-dimensionally arranged device regions and into a plurality of two-dimensionally arranged routing regions each crossing a plurality of boundaries between said plurality of device regions, such that said plurality of routing regions are shifted from said plurality of device regions by a distance,
- a plurality of device groups each including one or more semiconductor devices among said plurality of semiconductor devices and a local interconnect for connecting said semiconductor devices included in each said device group are disposed within said plurality of device regions, such that each boundary between said plurality of device regions is not crossed by said device group and said local interconnect, and
- a global routing for connecting said device groups to each other is disposed on said local interconnect within said plurality of routing regions, such that each boundary between said plurality of routing regions is not crossed by said global routing.
