Abstract
A method for processing design pattern data of a semiconductor integrated circuit includes determining whether or not there are lower-level cells whose individual size is equal to or below a threshold, and if there are such lower-level cells whose individual size is equal to or below the threshold, collecting the lower-level cells to define a higher-level cell whose size is greater than the threshold and replacing the lower-level cells with the higher-level cell.

A method for processing design pattern data of a semiconductor integrated circuit, comprising:
- determining whether there are lower-level cells whose individual size is equal to or below a threshold;
- if there are such lower-level cells whose individual size is equal to or below the threshold, pairing a first lower-level cell with a second lower-level cell, that is adjacent to the first lower-level cell, to define a new cell whose size is greater than the threshold;
- and
- replacing the first and second lower-level cells with the new cell.
A method for processing design pattern data of a semiconductor integrated circuit, comprising:
- determining whether there are lower-level cells whose individual size is equal to or below a threshold;
- and
- if there are such lower-level cells whose individual size is equal to or below the threshold, combining the lower-level cells to define a new cell whose size is greater than the threshold;
- and
- replacing the lower-level cells with the new cell;
- wherein the threshold is twice as large as the frame width which is a distance to be referred to when carrying out pattern data processing.
A computer program product for processing design pattern data of a semiconductor integrated circuit, comprising:
- instructions which determine whether there are lower-level cells whose individual size is equal to or below a threshold;
- instructions which pair, if there are such lower-level cells whose individual size is equal to or below the threshold, a first lower-level cell with a second lower-level cell that is adjacent to the first lower-level cell, to define a new cell whose size is greater than the threshold;
- and
- instructions which replace the first and second lower-level cells with the new cell.
