===Interconnect capacitance===
Traditionally, switching time was roughly proportional to the gate capacitance of gates. However, with transistors becoming smaller and more transistors being placed on the chip, [[capacitance|interconnect capacitance]] (the capacitance of the metal-layer connections between different parts of the chip) is becoming a large percentage of capacitance.<ref>{{cite web|url=http://www.research.ibm.com/journal/rd/293/ibmrd2903G.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://www.research.ibm.com/journal/rd/293/ibmrd2903G.pdf |archive-date=2022-10-09 |url-status=live|title=VLSI wiring capacitance|date=9 February 2021 |publisher=IBM Journal of Research and Development}}{{dead link|date=June 2015}}</ref><ref name=Soudris>{{ cite book | editor1-first = D.|editor1-last= Soudris|editor2-first=P.|editor2-last=Pirsch|editor3-first=E.|editor3-last=Barke | title = Integrated Circuit Design: Power and Timing Modeling, Optimization, and Simulation (10th Int.
