introduction to electromigration-aware physical design
Electromigration is increasingly relevant to the physical design of electronic circuits. It is caused by excessive current density stress in the interconnect. The ongoing reduction of circuit feature sizes has aggravated the problem over the last couple of years. It is therefore an important reliability issue to consider electromigration-related design parameters during physical design. In this talk, we give an introduction to the electromigration problem and its relationship to current density. We then present various physical design constraints that affect electromigration. Finally, we introduce components of an electromigration-aware physical design flow.
