Abstract :
Techniques for driving long interconnections in VLSI circuits are considered. Methods based on regularly inserted repeaters are reviewed, and it is shown that one of these is optimal. The main conclusions are that with the most accurate model of an interconnection (a π-model) used, the optimal repeater is an appropriately sized inverter and that, when the interconnection is resistive, a double-stage repeater performs better than an exponential horn of inverters
