In every digital ckt book we have a chapter on logic families which explains the rtL,TTl,emitter coupled, cmos mos etc.
What is the practical application of this? I can understand what is written in the book. (using book by Mano)
How does this help say to a person who is doing to do vlsi?
This gives the basic knowledge of Digital Logic Families and also the interfacing between any logic families depending on their logic levels.
So, In VLSI, it helps in making digital circuits.
it is akin to menu card in a hotel....depend upon ur carvings(design needs) u can pick a device....area, prog. delay,noise margin,power consumption and so many are factors that plays pivtol role in selection
guys,
from what i read is that the chapter explains terms such as fan in etc and gives a few gate construction using transisitor cmos etc. but how does that help in vlsi?
without knowing the fan out and fan in if you design a module and if you find later that you have crossed the maximum fan in at a particular parts of your design.... then you will have time constraint problem which may even lead to redesigning everything...
