Final <strong>Placement</strong> – St<strong>and</strong>ard Cell Designs<br />

This process continues until there are only a<br />

few cells in each group( ≈ 6 )<br />

group: smallest partition<br />

each group<br />

has ≤ 6 cells<br />

Assign cells in each<br />

group close together in<br />

the same row or nearly<br />

in adjacent rows<br />
