Abstract
According to at least one embodiment, a system comprises a region generation engine operable to create a region automatically around a portion of a clock trunk in a block, wherein the region defines an area for placement of selected cells, an automatic cell placer operable to place the cells in the region, and a routing engine operable to route signal wires from the clock trunk to the cells automatically according to one or more functions.
Claims26
A system comprising:
- a region generation engine operable to create a region automatically around a portion of a clock trunk in a block, wherein the region defines an area for placement of selected cells;
- an automatic cell placer operable to place the cells in the region;
- and
- a routing engine operable to route signal wires from the clock trunk to the cells automatically according to one or more functions.
1 more element
A method comprising:
- placing each of one or more clock trunks in one or more power/ground rails;
- routing the clock trunks into a block;
- automatically creating a cell region around at least a portion of each trunk within the block.
A system comprising:
- means for routing a clock trunk into a block between a power/ground rail;
- means for automatically creating a cell region immediately surrounding a portion of the trunk in the block;
- means for placing one or more sequential cells in the cell region;
- and
- means for routing one or more clock signals to the sequential cells from the trunk.
2 more elements
A system comprising:
- a circuit design, which includes:
- a clock trunk;
- a power/ground rail;
- a block, wherein the clock trunk runs inside the power ground rail and is routed into the block;
- and
- a sequential cell region, wherein the sequential cell region is automatically created inside the block to surround at least a portion of the clock trunk that is in the block.
