Medium scale integration has
Small scale integration has one or more logic gate. Further improved technology is medium scale integration which consists of hundred logic gates. Large scale integration has thousand logic gates.
The difficulty in achieving high doping concentration leads to
As photolithography comes closer to fundamental law of optics, achieving high accuracy in doping concentration becomes difficult, which leads to error due to variation.
_________ is used to deal with effect of variation
Designers must simulate multiple fabrication process or use system level technique for dealing with effects of variation.
As die size shrinks, the complexity of making the photomasks
As the die size shrinks due to scaling, the number of die per wafer increases and the complexity of making the photomasks increases rapidly.
______ architecture is used to design VLSI
SoC that is system on a chip architecture is used to design the very high level integrated circuit.
The design flow of VLSI system is1. architecture design 2. market requirement 3. logic design 4. HDL coding
The order of the design flow of VLSI circuit is market requirement, architecture design, logic design, HDL coding and then verification.
______ is used in logic design of VLSI
First in first out (FIFO) technique and finite state machine technique is used in the logic design of the VLSI circuits.
Which provides higher integration density?
Transistor-transistor logic offers higher integration density and it became the first integrated circuit revolution.
Physical and electrical specification is given in
Functional design defines the major functional units of the system, interconnections, physical and electrical specifications.
Which is the high level representation of VLSI design
Problem statement is a high level representation of the system. Performance, functionality and physical dimensions are considered here.
