Digital VLSI circuits are predominantly CMOS based. The way normal blocks like latches and gates are implemented is different from what students have seen so far, but the behavior remains the same. . Let us look at some of the factors involved,
CIRCUIT DELAYS
Large complicated circuits running at very high frequencies have one big problem to tackle propagation of signals through gates and wires .
POWER
Another effect of high operation frequencies is increased consumption of power. This has two-fold effect - devices consume batteries faster, and heat dissipation increases
LAYOUT
Laying out the circuit components is task common to all branches of electronics. What’s so special in our case is that there are many possible ways to do this; there can be multiple layers of different materials on the same silicon, there can be different arrangements of the smaller parts for the same component and so on.
