Abstract
A method for generating legal colorable multiple patterning standard cell placement is provided. In this method, a standard cell library including color information can be accessed. For each standard cell, edge labels can be assigned based on colors of objects within a predetermined distance from each edge. A truth table, which indicates legal spacing between pairs of standard cells based on their edge labels, can be accessed. A plurality of standard cells of a design can then be placed based on the truth table.
