Electronics is basically achieved by Circuits.
Circuits can be divided into Discrete Circuits and Integrated CircuitsIf we can not put everything into an IC and if some ready made components are available, we use them to achieve Electronics Circuits, This is called Discrete. This field is called HARDWARE.
We collect all the components and connect them in a PCB, Since these components are soldered to the PCB and Circuit is printed on the board, it will be difficult to change. But ultimately to make an Electronics product, HARDWARE is must. So requirement for an HARDWARE Engineer is always there.In ICs, three are three types.
1. ASIC – Fixed Circuit fabricated inside Silicon
2. FPGA – Flexible Circuit (Configurable) fabricated inside Silicon
3. µP – Flexible Circuit (Programmable) fabricated inside Silicon
ASIC – Low power, Cheap on high volume, Small in size and Fast . Butinvest will be huge. Normally big companies do thisactivity. Requires VLSI (verilog, VHDL, C++, Digital) KnowledgeFPGA – High Power, Cheap on Low Volume, Fast – But take more timeto implement. Requires VLSI (verilog, VHDL, C++, Digital)KnowledgeµP – High Power, Cheap, Slow. Easy to use. Requires Programmingknowledge(C, C++).ASIC and FPGA implementation is called VLSI and µP implementation is called Embedded.
Both VLSI and Embedded fields are having high demand. Since ECE students are generally not learning programming as part their course work, Industry is preferring CSE students for Embedded. That is the reason ECE students find it difficult to enter into Embedded field and feels that no job opportunity in Embedded field. Actually lots of job opportunities in Embedded field, but ECE students can get these jobs because they lack programming ability.Even VLSI field is all about programming, but this field requires Electronics knowledge also. That is the reason CSE students could not able to enter into VLSI and industry prefers ECE students. That is reason ECE students think lots of job opportunities in VLSI.
Actually Embedded Job Opportunities are much more than VLSI. Since ECE and CSE both enter into Embedded, Embedded Job opportunities looks less for ECE students.As of today both these fields are having enormous job opportunities. It is upto the student, how he prepare for these fields during their studies. If you follow our Indian University Syllabus and teaching (most of the universities), you will come out as useless with a degree paper and only eligible for IT support services and BPO jobs. So plan carefully during you degree. Utilize your time very effectively. Do not depend on your college for Knowledge or Skill on these fields.Actually, both of them. Embedded systems in its very early stages in India. Though I can see it growing at very very great pace!Talking about VLSI, it’s also in early stages. Umm.. Wait, you can actually say that it progress in Indian market is negligible and its growing at competitively slow rate. We need better government policies for the progress of this field.You’ll find many startups in embedded system but not a single semiconductor plant in India.as far as no. of opportunities , Embedded have more no. of jobs in India.And if your concern is about growth, both are nearly same.
