VLSI is Very Large System Integration
Today, instead of using vacuum tubes (which were used in electronic products a few decades ago), transistors are used. the biggest (but not the only) advantage of the transistors is the size - instead of having a vacuum tube that id 1-2 cm, a single transistor is around 40 nm (nano meter) - 25000000 times smaller!!!!
it means that one can create a very complex system, with tens of thousands of transistor, on a single chip that is in the size of 1x1 cm. In other words, one can integrate many complex modules in his system.
The problem is that when a human being is designing such a complicated system, there are many mistakes because of the system's complexity. Therefore, it takes a very careful process of checks and verifications when designing such a system
LSI is a large scale integration technology. VLSI is a very large scale integration technology. LSI deals with fabricating 100s of devices at a time on a single IC whereas, VLSI deals with 1000s.
VLSI Technology was created in 1979.
VLSI Technology ended in 1999.
sum of the applications of VLSI are chip like microcontroller,microprocessor,mobile etc
VLSI Era:- Very Large Scale Integration Era
to say frankly it is still a confusion thing for me to decide vlsi is either hardware or software,but according to my opinion vlsi is both hardware and software.
how to make a chip ---- vlsi how to use a chip ---- embedded systems
i want previous vlsi question papers
VLSI is combined of both theory and derivation with more diagrams
there are a number of directionsa person can take in vlsi,and they are all closely related to each other.
If you are looking for an introductory text on algorithms for VLSI design automation, I recommend: Sabih H. Gerez, Algorithms for VLSI Design Automation, John Wiley and Sons, Chichester, (1999).
