Recent Trends in the VLSI Design Industry – Growth Drivers
Internet of Things (IOT) is
considered to be the next big thing
with more than 50 billion devices
expected to be connected to the
Internet by the year 2020.
Any IOT System can have the
following components.
o Data acquisition (Sensors,
Actuators)
o Data Transport (High Speed
Wired or Wireless Links)
o Data Storage, Processing
and Analysis (Memory, Cloud
Computing, Big Data, Processors,
Microcontrollers)
o Actions based on the
The India Context
Apart from the global demand and growth prospects in Electronics, India is being
confronted with a special problem with respect to Electronics manufacturing.
The top three imports India make from other nations are
 Petroleum
 Gold
 Electronics
The India Context
The India Context
 This means, by the year 2020, electronics will surpass Oil as the largest imported
item in India, thereby creating a huge trade deficit for the country.
 To bridge this gap, the Indian Government has brought in lots of new policies to
encourage domestic electronics production, including Semiconductor design
companies, electronic device and equipment making companies.
 The Government is also working on setting up of state of the art Wafer Fabs and
many manufacturing clusters in India.
National Policy on Electronics
Skill India, SMDP
Digital India, Smart Cities

VLSI Design and the North-East Region of India
 Even though there are engineering colleges in Manipur and other states in the
North East region of the country, there has been less awareness about the
opportunities in VLSI design domain.
 In other parts of India, there are collaborations between various Universities and
Companies to train engineering graduates to make them ready to work in the
industry by the time they complete their engineering graduation.
 However, such collaborations are rare in the North East Region due to lack of
awareness and initiatives. Seeing some welcome changes.
 VLSI Training Institutions
 Cost of EDA Tools
The region does not
exist in the VLSI Design
Map of India !
Demand for VLSI Design Engineers in India
 India - One of the Semiconductor design hubs of the world.
 Semiconductor multinational companies. INTEL, QUALCOMM, BROADCOM, ARM,
Texas Instruments, Sandisk, NXP, Samsung.
 More than 250+ small and medium size design companies in India.
 Major design service companies like Altran, Aricent, Wipro, Sankalp etc.,
supporting supports the MNC companies with their engineering staff.
 There are also companies that focus on turnkey design of ASICs, Analog macros
and provide R&D Services like ELVEEGO CIRCUITS.
 The number of Engineers with very niche skills like Analog Design are less and
they are in huge demand in the industry.
 Other skills like Analog Layout, Digital Physical Design, Verification are also in
demand as the volume of such work happening in India is very large.
Demand for VLSI Design Engineers in India
 The Government of India has also launched schemes like Special Manpower
Development Plan and is pushing hard to create Human resources.
 In the last couple of years or so, the demand for highly skilled VLSI design
engineers is such that, it is very common to find experienced engineers having job
offers from 3-4 companies at the same time.

 The domain of VLSI is vast.
 And, irrespective of the specialization one wants to be in, good knowledge on the
following is required to be in this domain.
o Basic Electronics – Devices and Circuits
o Basic Engineering Mathematics
o Switching Theory
o Logic Design and Digital Electronics
o Network Analysis and Synthesis
o Unix/Linux Basics

o Analog Building Blocks like Opamps, Voltage and Current References,
Clock Circuits, PLLs, Data Converters etc.,
o Layout Concepts
o CMOS Technology, Device modelling and Fabrication process
o Usage of EDA Tools, Design and Verification Methodologies
Skills required to be in the VLSI Design Industry
 To excel in Digital Design, one need to have command in:
o Logic Design and Timing Analysis
o Hardware Description Language (HDL) like Verilog or VHDL
o RTL coding , Functional verification,
o Synthesis, GLS, DFT,
o Clock Specification, Power Domain Definitions and STA, Scripting
languages such as Perl,
o Usage of EDA Tools, Design and Verification Methodologies
Skills required to be in the VLSI Design Industry
 There are some areas in VLSI which are comparatively easier to enter like:
o Analog Layout
o Analog and Mixed Signal Verification
o Digital Verification
o Digital Physical Design
 There are various VLSI design training institutions in places like Bangalore,
Hyderabad, Delhi offering advanced training courses with duration of 3-6 Months.
 The best way for a fresh engineering graduate to enter VLSI design is to intern at
a design company.
 Also getting 3-6 months of training from a specialized training institution and then
attempt to enter the industry as a fresher.
Demand, Gaps and Opportunities
 Catch 22 !
