What is VLSI?
VLSI (Very-large-scale integration) is a process that means to create integrated circuits by combining thousands of transistor-based circuits into a single chip. VLSI began in the 1970s when complex semiconductor and communication technologies were being developed. The microprocessor is a VLSI device. Nearly all modern chips employ VLSI architectures.
The first semiconductor chips held two transistors each. Subsequent advances added more and more transistors, and, as a consequence, more individual functions or systems were integrated over time. Current technology has moved far past this mark and today’s microprocessors have many millions of gates and billions of individual transistors.
Why VLSI Programming?
With the design & manufacturing market (both domestic & international) expanding rapidly, there is an enhanced demand of trained professionals who will boost the technical work force in the VLSI domain.
There is a rising demand for chip driven products in consumer electronics, medical electronics, communication, aero-space, computers etc.
More and more chip designing companies have set up their units in India eying on the Indian talents; besides many of the Indian Major IT companies have forayed in Application Specific Integrated Circuit (ASIC) design in a big way.
