Introduction

What is Digital Design Automation about? What is VLSI? Why do we have to study this subject?


Why VLSI?

Integration improves the design: lower parasitics = higher speed; lower power; physically smaller.

Integration reduces manufacturing cost-(almost) no manual assembly.


VLSI and you

Microprocessors: personal computers; microcontrollers.

DRAM/SRAM. Special-purpose processors.


Why build integrated Circuit?

IC Technology driving the whole innovative devices and systems which effected the way we live. ICs are much smaller. consume less power than discrete component. easier to design and manufacture. more reliable than discrete system. can design more complex system.

The growth of electronic industry.


Example of VLSI application

Electronic system in cars. Digital electronics control VCRs Transaction processing system, ATM Personal computers and Workstations Medical electronic systems. etc….


The advantageous of digital ICs over the discrete components (1/2)

Size much smaller both transistor and wires. leads to smaller parasitic resistances, capacitanc

es and inductances Speed

communication within the chips are much faster than between a chips on PCB.

High speed of circuits on-chip due to smaller size.


The advantageous of digital ICs over the discrete components (2/2)

Power Consumption Logic operation within th

e chip consumes much le

ss power.

smaller size -> smaller p

arasitic capacitances and

resistance -> require less

power to drive the circuit.


Advantages of IC at System Level(1/2)

Smaller Physical Size can make a small electronic appliances. ie. portab

leTV, handheld cellular telephone…

Lower Power Consumption reduce total power consumption on a whole elect

ronic circuit. cheaper power supply which leads to a simpler ca

binet for power supply. Less heat, Fan may no longer be necessary.


Advantages of IC at System Advantages of IC at System LevelLevel(2/2)(2/2)Advantages of IC at System Advantages of IC at System LevelLevel(2/2)(2/2)

Reduce Cost Reducing in number of components.

Power Supply requirement.

Cabinets

The cost of building a whole system is reduce ev

enthough Ics cost more.


The cost of fabrication

Current cost: $2-3 billion.

Typical fab line occupies about 1 city block, employs a few hundred people.

Most profitable period is first 18 months-2 years. Pentium® 4 “Northwood”

55M transistors / 2-2.5GHz L=0.13µm


Cost factors in ICs

For large-volume ICs: packaging is largest cost; testing is second-largest cost.

For low-volume ICs, design costs may swamp all manufacturing costs.


Integrated Circuit Manufacturing

Technology Let us build a system faster, and more complex s

ystem

Economics In 1960s,Gordon Moore said that the number of tr

ansistor would grow exponentially. The number of transistors per chip has doubled about once a year.

IC plant is very expensive. $2-3billion or more. Is it worth to invest in IC business?


Challenges in VLSI design

Multiple levels of abstraction: transistors to CPUs.

Multiple and conflicting constraints: low cost and high performance are often at odds.

Short design time: Late products are often irrelevant.
