how does wire geometry affect the vlsi design
Answers
Answer:
In this chapter, we will investigate some of the physical factors which determine and ultimately limit the performance of digital VLSI circuits. The switching characteristics of digital integrated circuits essentially dictate the overall operating speed of digital systems. The dynamic performance requirements of a digital system are usually among the most important design specifications that must be met by the circuit designer. Therefore, the switching speed of the circuits must be estimated and optimized very early in the design phase.
The classical approach for determining the switching speed of a digital block is based on the assumption that the loads are mainly capacitive and lumped. Relatively simple delay models exist for logic gates with purely capacitive load at the output node, hence, the dynamic behavior of the circuit can be estimated easily once the load is determined. The conventional delay estimation approaches seek to classify three main components of the gate load, all of which are assumed to be purely capacitive, as: (1) internal parasitic capacitances of the transistors, (2) interconnect (line) capacitances, and (3) input capacitances of the fan-out gates. Of these three components, the load conditions imposed by the interconnection lines present serious problems.
