Many p h ysical synthesis tools interdigitate signal and power lines to reduce cross-talk, and thus, improve signal integrity and timing predictability. S u c h approaches are extremely e ective at reducing cross-talk at circuit speeds where inductive e ects are inconsequential. In this paper, we u s e a detailed distributed RLC model to show that inductive cross-talk e ects are substantial in long busses associated with 0.18 micron technology. Simulation experiments are then used to
more » ... that cross-talk in such high speed technologies is much better controlled by re-deploying interdigitated power lines to perform di erential signaling.
