VLSI - Verilog HDL

Verilog is a Hardware Description Language which is used to model complex electronic components. It is standardized as 1364. It is commonly used for two purposes. They are:

  • Design.
  • Verification of digital circuits.

It is basically used for verification of analog circuits and mixed-signal systems. Verilog as Hardware Description Language includes signal strengths and considers way of describing the propagation time which differentiates it from the software programming language. Verilog HDL is easier to learn as compared to VHDL due to emphasis on C language.

Verilog HDL is also case-sensitive and is not strongly typed. It has very simple data types but lacks the library management as compared to VHDL. It is a very important sub domain of VLSI and forms part of front end.


VLSI stands for “very large scale integration” determines integration levels. Apparatus of transistor was the driving factor of growth in the VLSI Technology. VLSI is a Technology by which 10000-1 Million Transistors can be assembles on a single chip.

VLSI has many advantages:
1. Curtail the size of Circuits.
2. Curtail the efficient cost of the devices.
3. Escalation the Operating breeze of circuits.
4. Crave less power than Discrete factor.
5. Bigger Reliability

VLSI as an industry is highly rewarding for engineering students who have good grasp of the concepts and performing ability. The students trained in VHDL are in huge demand in India and abroad. According to the industry experts and joint report of India Semiconductor Association (ISA) and Ernst & Young, the semiconductor industry is expected to grow at 17.4% to reach around $10 billion in 2014.

There is a huge demand for skilled engineers to develop Field Programmable Field Array (FPGA), Application Specific Integrated Circuits (ASIC) and SOCs, so it becomes quite obvious that students should foray their career in this industry and get exposed to patent filing, invention disclosures and applied research.
