  • In common, most circuits of interest can be realized as an RC tree, i.e., an RC circuit with no loops.
  • The root of the tree will be the voltage source and the leaves will be the capacitors at the ends of the branches.
  • The Elmore delay model determines the delay from a source switching to one of the leaf nodes changing as the sum over each node I of the capacitance Ci on the node, multiplied by the effective resistance Ris on the shared path from the source to the node and the leaf.
