  1. CSE 252A Integrated Circuit Layout Automation Lecture 2: ITRS Roadmap and Lower Power Design Methodology Winter 2009 Chung-Kuan Cheng

  2. Agenda • Scaling • ITRS Roadmap

  3. Scaling -- Gate Drain Scaling Factor is S Drain Gate Source Source

  4. Scaling -- Gate • Capacitance is proportional to S • Voltage is proportional to S • Frequency is inverse proportional to S

  5. Scaling – Transmission Line W W

  6. Interconnect • Ways to reduce interconnect power consumption • Shorter wire length • More spacing • Clock gating
