摘要:
A method is presented for incorporating skip vias in a place and route flow of an integrated circuit design. The method includes employing a place and route tool to add the skip vias, each skip via extending through a metallization layer to electrically connect a metal layer above the metallization layer to a metal layer below the metallization layer and, when a violation of a design rule is detected due to the addition of one or more of the skip vias, substituting skip vias that violate the design rule with a standard via.
