The document discusses VLSI (Very Large Scale Integration) design, emphasizing Moore's Law and its implications for technology improvements. It outlines various IC products, design styles, and the role of software tools in VLSI design, including programmable logic and system-on-chip (SoC) concepts. Additionally, it highlights the growing VLSI design sector in India and the emergence of startups in this field.

4. Moore’s Law
 Gordon Moore: co-founder of Intel
 Predicted that the number of transistors
per chip would grow exponentially (double
every 18 months)
 Exponential improvement in technology is
a natural trend:
e.g. Steam Engines - Dynamo - Automobile

9. VLSI Design Styles
 Full Custom
 Application-Specific Integrated Circuit
(ASIC)
 Programmable Logic (PLD, FPGA)
 System-on-a-Chip
electrohybrideTech

10. Full Custom Design
 Each circuit element carefully “handcrafted”
 Huge design effort
 High Design & NRE Costs / Low Unit Cost
 High Performance
 Typically used for high-volume applications

11. Programmable Logic (FPGA)
 Pre-manufactured components with
programmable interconnect
 CAD tools greatly reduce design effort
 Low Design Cost / Low NRE Cost / High Unit
Cost
 Lower Performance

12. System-on-chip (SOC)
 Idea: combine several large blocks
 Predesigned custom cores (e.g., microcontroller) -
“intellectual property” (IP)
 ASIC logic for special-purpose hardware
 Programmable Logic (PLD, FPGA)
 Analog
 Open issues
 Keeping design cost low
 Verifying correctness of design

13. Software tools
 Simulator ( verilog & VHDL)
 Model sim HDL
 Cadence NC
 Iverilog
 Synthesis tools
 Precision RTL
 Leonardo spectrum
 Questa sim

14. Development tools
 Xilinx ISE
 Altera Quartus II

15. Scenario in India???
 HUGE outsourcing
 Loads of startups (WHY?)
 VLSI design is nowhere a single nation job
 Fabrication labs (fabs) in USA getting sold
out
 India getting 4 fabs by next year!
