The Chips are up...



May the peace and blessings of the Almighty be upon us...

Few years back, Mr. Jhinuk Chowdhury of TIMES GROUP wrote a very insightful article named “THE CHIPS ARE UP”. This piece analyses the future opportunities in the field of Semiconductor/VLSI and the challenges faced by Electronics/Electrical engineers. I give the entire article below and hope this will be of immense use. 

"
The semiconductor industry is set to add around 3.5 million heads by 2015 to its existing count of 20,000. Jhinuk Chowdhury learns more about the opportunities that this industry offers

    Just being an electronic engineer doesn’t qualify you to get a job in the semiconductor industry. You need to have a hunger to learn. A burning desire to know how things work and a background of dismantling electronic toys to understand how they function, would also go a long way. If the above mentioned is an extension of your profile, then the semiconductor industry is looking for you. Companies like Freescale, Texas Instruments, KPIT Cummins, Cadence, STMicroelectronics and many more are recruiting electronic engineers with excellent analytical aptitude and quick learning abilities at salary packages higher than those offered by the IT industry. One small deterrent here is that academia provides for only 20 per cent of the required manpower. To give you an industry example, while KPIT Cummins needs 150-200 people every year, it only manages to find 80 relevant candidates. So, while the talent crunch is evident, the industry looks more promising than ever. Let’s find out why one should should opt for this industry and who gets in. 



 NEW FUNCTIONS 

Job creation in this sector would be in the areas of Integrated Circuit (IC) Design, VLSI, EDA (electronic design automation), manufacturing operations related to testing, packaging, logistics etc. 

    The industry is hiring Electronics/Electrical engineering professionals with knowledge of digital design, simulation, synthesis tools, computer architecture, and mixed signal design, and strong mathematical aptitude. Also, a fair knowledge of different sectors, like consumer electronics, mobile devices, home security systems, auto components etc. are absolutely essential. This however does not undermine the need for behavioural skills. As for Philips Electronics India Ltd, while technical competencies are a must, behavioural aspects are just as important. Says Rajeev Mehtani, VP & Site Innovation Manager, Philips Semiconductors, “We look for a mindset committed to quality, and a ‘not giving up’ attitude with global perspective.” The Philips Innovation Campus at Bangalore, has, as of now, been awarded 16 patents. 

DRAFTING A CAREER PATH 

    As mentioned above, one of the factors that would draw most candidates towards this industry is the generous compensation offered. Poonam Shenoy, ISA agrees that the salaries offered in this industry are much higher than any other technology industry, “It starts from Rs 4.5 lakhs which is significantly higher to what is offered by the software industry.” Veena Kumar, HR Manager, Open Silicon, even feels that it might go upto Rs 6.5 lakh for a fresh graduate who displays the right aptitude and is a logical fit. 

    In terms of vertical growth, one can start as a research and design engineer and move up to a project leader, a senior design engineer, or systems architect. 

WAY TO GO 

Says B S Murphy, CEO, Human Capital, “We have always underplayed our Math strength, whereas the industry needs super math and algorithm skills.” Another key issue is the lack of training facilities. Praveen Acharya, VP-ATS, Semiconductor Group KPIT, feels that academia has, so far, given almost a ‘stepmotherly’ treatment to the semiconductor industry. Girish Wardadkar, President & ED, KPIT, feels India is no match to the semiconductor manufacturing activities happening in China, “China is definitely more appealing to chip manufacturing firms in the US and UK, which explains why India, today, may have an edge in design services but not manufacturing.” 

    An ecosystem needs to be created where the industry and academia join hands to identify the global needs of the industry and churn out relevant engineers. Exclusive design schools validated by the industry and sponsorship of laboratories could definitely accelerate the process of further developing this industry"

SMVEC workshop pics...



May peace and blessings of the Almighty be upon us all..

The company I belong to, Bistate Systems, conducted five days onsite training program (or workshop) in VLSI DESIGN, recently, at one of the popular educational organizations of Pondicherry, Sri Manakula Vinayagar Engineering College (SMVEC). This workshop, in which, I trained the students of Instrumentation & Control Engineering (Third year) on the basics of VLSI Design, is a part of Industry-Institute interaction on knowledge sharing. 

Response from the students was very encouraging and positive (All praise to the Almighty). I thank the management, teaching staff & the assisting staff for the excellent hospitality provided. The workshop went like this, technical sessions with practical knowledge along with competitive assessments. Certificates were provided on the basis of ranks secured at the competition. Here are some of the pics of the moment...












God Willing, we will meet in a another blog post.

What is NRE Cost?



May peace and blessings of the Almighty be upon you all..

One of the most important parameters in VLSI world is Non-Recurring Engineering cost. Every company want their NRE cost to be lower. What is it? Why it is very important?

In simple terms, NRE cost is the cost invested on a particular project that cannot be recovered back. 

To explain this, let us see a case where you are developing an ASIC for a company. You spend quite a good amount of money on manpower, design, fabrication etc. What will happen if the resulting product does not meet up to your client’s expectations? Money spent on them cannot be recovered and adding to that you need to design the product again with another NRE cost set. As you see, the money invested on this project is gone and you cannot recover it. 

This is why ASICs have high NRE costs associated with them. Since there is no fabrication involved with Programmable devices (PLDs / FPGAs), they preferably have less NRE cost spent on them due to reprogrammable ability.

Deciding between ASICs and FPGAs...



May peace and blessings of the Almighty be upon you all..

Deciding between ASICs and FPGAs requires designers to answer tough questions concerning costs, tool availability and effectiveness, as well as how best to present the information to management to guarantee support throughout the design process.

The first step is to make a block diagram of what you want to integrate. Sometimes it helps to get some help from an experienced field applications engineer. Remember that time is money. Your next move is to come up with some idea of production volume. Next, make a list of design objectives in order of importance. 

These could include cost, die size, time-to-market, tools, and performance and intellectual property requirements. You should also take into account your own design skills, what you have time to do and what you should farm out. Remember that it must make sense financially or you are doomed from the start. 

Time-to-market is often at the top of the list. Some large ASICs can take a year or more to design. A good way to shorten development time is to make prototypes using FPGAs and then switch to an ASIC. But the most common mistake that designers make when they decide to build an ASIC is that they never formally pitch their idea to management. Then, after working on it for a week, the project is shot down for time-to-market or cost reasons. Designers should never overlook the important step of making their case to their managers.

Before starting on an ASIC, ask yourself or your management team if it is wise to spend $250,000 or more on NRE costs (The cost that is invested on the project that cannot recovered back. Example: fabrication charges during ASIC). If the answer is yes and you get the green light, then go. If the answer is no, then you'll need to gather more information before taking the ASIC route. Understand that most bean counters do not see any value in handing someone $250,000 for a one-time charge. They prefer to add cost to the production.

Say your project has a NRE of $300,000, a volume of 5,000, and it replaces circuitry that costs $80. The final ASIC cost is $40. You do some math and determine the break-even point is three years. If you amortize the same design over five years, this could save your company $400,000 even after NRE has been absorbed. 

Another option is to do a "rapid ASIC" using preformed ASIC blocks, which saves time and lowers NRE costs. It could also make sense to convert an FPGA to ASIC directly, which lowers NRE a small amount from the rapid type. 

Now let's say your company will not fund an ASIC effort. That means it's time to consider FPGAs. First, be aware that while the tools are free on the Web for the smaller FPGAs, you'll have to pay for a license file for the ones with high gate counts. The good news is that there are no NRE charges. 

Modern FPGAs are packed with features that were not previously available. Today's FPGAs usually come with phase-locked loops, low-voltage differential signal, clock data recovery, more internal routing, high speed (most tools measure timing in picoseconds), hardware multipliers for DSPs, memory, programmable I/O, IP cores and microprocessor cores. You can integrate all your digital functions into one part and really have a system on a chip. When you look at all these features, it can be tough to argue for an ASIC. 

Moreover, FPGA can be reprogrammed in a snap while an ASIC can take $50,000 and six weeks to make the same changes. FPGA costs start from a couple of dollars to several hundred or more depending on the features listed above. So before you get moving, make sure to enlist some help, get the managers to support you, come up with a meaningful cost estimate, choose the right weapon — be it ASIC or FPGA — and then move into production.

By referring to previous posts in this blog, we will organize the differences between ASICs and Programmable logic devices (CPLDs/FPGAs) in a table which is presented in the next page. The below table discusses about the differences between Programmable devices and ASICs.
