ECE 124d/ ECE 256c Lab 2 This lab is in two parts, in the first you characterize some representative RC buffering cases, and in the second part, you optimize buffer insertion for practical case. Part a (due Jan. 26, 2011), Part b (due Feb., 3, 2011). Part a: Modeling In this lab, you will start with a general distributed LRC model and reduce it to a much simpler model while determining the accuracy of the approximation. First, build a distributed wire model as was done in the first lab, using an LRC distributed model (neglect G). The physical parameters of the wire are as follows: 1. Wire width 210nm 2. Wire thickness: 400nm 3. Material: Cu 4. Distance to substrate from base of wire: 1.2um 5. Dielectric Constant of media: (effective) 2.9 ε 0 As an approximation of distributed RC lines, Pi-models are commonly used, as are simple lumped Elmore delay models. A pi model for a distributed RC segment models the total resistance as three serial resistors (R/3), with two (C/2) capacitors to ground at the two internal junctions. This
