Introduction
What is Digital Design Automation about? What is VLSI? Why do we have to study this subject?
April 7, 2023 204424 Digital Design Automation6
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
April 7, 2023 204424 Digital Design Automation15
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?
April 7, 2023 204424 Digital Design Automation17
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.
