Local and Global Interconnects
Modeling Interconnects – capacitance of a single wire-
wires everywhere!
Modeling Interconnects – capacitance of two wires-
Modeling Interconnects –layout capacitance example-
Interconnect resistance
Estimating resistance of a wire –measuring squares-
Interconnect resistance scaling
Via resistance
Modeling interconnects
Distributed: (R-C)
Lumped parameter: (C)
Simulation
