Abstract
A chip includes a first column including first rails extending in a first direction, the first rails having a first pitch. The chip also includes a second column including second rails extending in the first direction, the second rails having a second pitch different from the first pitch. The chip also includes a transition region between the first column and the second column.
Claims18
A chip, comprising:
- a first column comprising first rails extending in a first direction, the first rails having a first pitch;
- a second column comprising second rails extending in the first direction, the second rails having a second pitch different from the first pitch;
- and
- a transition region between the first column and the second column,
- wherein an edge of the first column abuts a first edge of the transition region, an edge of the second column abuts a second edge of the transition region, the second edge opposing the first edge, and
- wherein the first rails are cut at the first edge and the second rails are cut at the second edge.
3 more elements
A chip, comprising:
- a first column comprising first cells arranged in first rows, wherein each of the first rows comprises respective one or more of the first cells, and each of the first rows extends in a first direction;
- and
- a second column comprising second cells arranged in second rows, wherein each of the second rows comprises respective one or more of the second cells, and each of the second rows extends in the first direction;
- wherein each of the first cells is shorter than each of the second cells in a second direction, and the second direction is perpendicular to the first direction.
1 more element
A method for chip layout, comprising:
- receiving an indication of first cells and second cells to be placed on a chip, wherein each of the first cells is shorter than each of the second cells in a first direction;
- determining an area of the first cells;
- determining an area of the second cells;
- determining a first width and a second width based on the area of the first cells and the area of the second cells, wherein the first width and the second width are in a second direction, and the second direction is perpendicular to the first direction;
- laying the first cells in first rows in a first column, the first column having a width approximately equal to the first width;
- and
- laying the second cells in second rows in a second column, the second column having a width approximately equal to the second width.
