I recently found out that I’ll be attending the Embedded Systems Conference in Chicago early next week. I also will be attending some of the events at Sensors Expo & Conference, which is being held in the same conference center. I couldn’t be happier that I get to attend two conferences in one shot AND that I get to visit Chicago in the process.

So why embedded systems? “I thought this was a site about analog electronics,” you say. Well, it is. But good luck making an all-analog system these days. These days, analog is more about signal conditioning, power, control and accuracy. I mean, everything is analog in the end. Even digital signals will look analog if you clock them fast enough; but the point is, digital is an important topic to know as well. Embedded systems let you interface to the fun analog systems at a lower level (think running code in C instead of a full blown implementation of Windows) so you can run your systems even faster, cheaper and using less power.

The sensors expo will fit in nicely. Sensors are what analog is built on. They are how electronics interact with the real world! So I look forward to reporting on all the new interface products that are out there.

Finally, this will be my first real conference, at least the first I’ve traveled to outside of a 30 mile radius of where I live. I’ve encountered conferences before–and the culture that they have–but never on a scale like this. It will be interesting to see an electronics conference this large. I recently read “Never Eat Alone” by Keith Ferrazzi. He has an entire chapter about the benefits of conferences, how to work them more effectively and most importantly, how to meet people. I hope to make some connections and add to the growing section on this site of interviews with people from industry.

What about you? Have you ever been to any large electronics conferences? Anyone happen to be going to these conferences? Any tips for this relatively new guy? Any new technologies I should be on the lookout for? Let me know in the comments!

I’ve asked communities I’m a part of where all the electronics sites are. The truth is there are some out there, and the popular ones are there for a reason. They produce a lot of great content and highlight engineers and hobbyists who really contribute a lot to their respective communities. But why aren’t there more? Are electronics just innately uninteresting? I don’t think so–obviously–or else I’d have a bit of a conflict of interests. So what is it that prevents more people from publishing sites about electronics?

1. Secrets
   • Even on my own site, I don’t write about my work. I go to work for 8+ hours a day and work on some really cool stuff. I enjoy it. But there’s no way I can talk about every problem I run into. That’d be ridiculous! Now contrast that with someone who works in politics. It’s all out in the open (at least it should be), and the rest is just opinion. As long as they don’t say something that will get their boss in trouble (or more likely, as long as they agree with their boss), the site is a boon. Same for PR, marketing and lots of other sectors. Blogs and websites about their work seems complimentary. Sure they don’t share everything about the behind the scenes, but in those cases, the more info that’s out there, the better. In engineering, it’s often the secret sauce of a company that is the most important…and also the most protected.
2. Access to Industry Info
   • So maybe you decide you’d like to write about a technology company from the outside. Lots of sites already do this kind of thing. There are tons of Apple fan sites, right? Well, yes, but again they’re writing about things that are public–or in recent times about phones that were found that weren’t meant to be public. The engineers behind the scenes at Apple can’t write about their experiences due to NDAs and trade secret protections. Nor for big companies with exciting products like Intel. Sure you can write about what’s out in the marketplace now (such as the i7), but you can’t write about how they tweaked with the design in order to make it better than previous generations. Nor can you write about the impressive geometry shrinking that is occurring to keep pace with Moore’s law and how that affects your EDA tools.
   • NOTE: I might consider industry magazines such as EETimes, EDN and Design News to be an example of companies that have access to industry info, EXCEPT I consider them as news sources about the industry and not about engineering.
3. The Speed of Science
   • Unfortunately, real science is slow. Even pseudo-science is slow, with the new hot products being released only so often. And beyond the discoveries being announced via PhysOrg or IEEE or Engadget, what is there? Whereas there may be political sites that can subsist on just reporting the news of the latest scandal (and all the details and conjecture associated with it), science and electronics has a limited amount of new information to report upon. Without as dynamic an atmosphere, there are bound to be fewer sites reporting on the news of the industry.

Of the sites that are out there about electronics, some really stand out in my mind. The Electronics Engineering Video (EEV) Blog, Chiphacker, Discovercircuits.com and so many more. They provide great services to people, which keeps them  coming back. But what about these sites really draws people in? I’ve pondered this question in terms of what might make more people want to read my site. Here’s what I’ve come up with:

1. Instruction
   • No doubt that people utilize the internet as an instructor for their latest projects. In fact, I’ve tailored some of my own more popular posts (about how op amps work) towards teaching people in certain niche areas. Some of the best sites out there (such as Instructables), helps people to learn about their project or the subject they are studying. The mere fact that they are offering free information (that is assumed to be correct) is a very big draw for the masses. Unfortunately, as far as competition goes, there are some major leaders in terms of “how things work” and the smaller players often fall off the map, hence fewer parties trying to explain a topic like when to use analog versus digital circuits.
2. Personal Projects
   • These sites are my personal favorite and easy to spot as a favorite of many others. Why? Because the site continues to showcase technology applications that likely have never been seen before. No, the technology itself is pretty standard; Arduinos and other simple microcontrollers are often the basis for many of the designs. However, the application is usually different and almost always intriguing. Sites such as Make magazine and Hack-a-day showcase the latest uses of technology in novel situation

While I don’t think the hardware sites have quite reached the critical mass that software development sites have reached, I’m not worried. The hobbyist movement continues to grow and I believe the general population has been re-warming to the idea of working on electronics (at least some part of the population, that is).  Given the slow uptake of the hardware community with new media, it’s not all that surprising that we haven’t seen as many sites as we might have expected. However, I think we’ll be seeing more soon. What do you think? Have I missed any big categories of websites? Or are hardware engineers and their respective interests always doomed to remain in the shadows?

Holidays have been used in the past to paste some pictures together for my background image. This time it was a change of role as well. As I’ve once stated, I don’t really like the “sustainability” title on things. It’s much too management whereas I like focusing on engineering. So I stuck to the “renewable energy” stuff, or so I said. In the meantime I’ve realized that I really don’t write about renewable energy anymore. It turned out it WAS a passing phase for me, as Cherish from “Faraday’s Cage is where you put Schroedinger’s Cat” once said in the comments of a post.

Don’t get me wrong, I like renewable energy. I like it a lot. It’s definitely important, especially given the oil snafu’s of late. But in terms of what I can add to the conversation and where I feel I fit best, I think I would choose analog electronics before renewable energy. Anyway, it doesn’t matter much; if I start writing about renewable energy a whole lot more, I’ll just change it back!

In other news, I’ve changed up the headings at the top of each page. I’ve removed some things and added another. As I’ve written about in the past, I’ve been searching for alternate sources of income. I’ve decided to offer my non-day-job time to anyone who needs help on their projects. No, it shan’t be free, but I will promise the first 3 projects 50% off my standard rate. If you have any needs for electronics projects, please look at the services I offer and how we might work together.  Then give me a shout and we’ll start working on your exciting new project together.

As more circuits get pushed into SoC (Systems on a Chip), the software that designs them becomes more and more important. Well, it’s been important for a while now. Important enough to be a multi-billion dollar industry. Biiiiig money.

Harry Gries is an EDA consultant with over 20 years in the electronics industry in various roles. He now consults for different companies and also writes a blog about his experience called “Harry…The ASIC Guy”. I love hearing about the different pieces of the electronics food chain and Harry was nice enough to take some time to talk to me about his work. Let’s see what he had to say…

CG: Could you please explain your educational and professional background and how you got to where you are today?

Harry The ASIC Guy (HTAG): My education began when I was raised by wolves in the Northern Territory of Manitoba. That prepared me well for a stint at MIT and USC, after which I was abducted by aliens for a fortnight. I then spent 7 years as a digital designer at TRW, 14 years at Synopsys as an AE, consultant, consulting and program manager. Synopsys and I parted ways and I have been doing independent consulting for 3 years now. A good friend of mine tricked me into writing a blog, so now I’m stuck doing that as well.

CG: What are some of the large changes you see from industry to industry? How does company culture vary from sector to sector?

HTAG: Let’s start with EDA, which did not really exist when the aliens dropped me off in 1985. There were a few companies who did polygon pushing tools and workstations and circuit complexity was in the 1000s of gates. Most large semiconductor companies had their own fabs and their own tools. Gate arrays and standard cell design was just getting started, but you had to use the vendor’s tools. Now, of course, almost all design tools are made by “EDA companies”.

As far as the differences between industries and sectors, I’m not sure that is such a big difference culturally. The company culture is set from the top. If you have Aart DeGeus as your founder, then you have a very technology focused culture. If you have Gerry Hsu (former Avant! CEO), then you have a culture of “win at all costs”.

CG: How hard was it for you to jump from being a designer to being in EDA? What kinds of skills would someone looking to get into the industry need?

HTAG: The biggest difference is clearly the “soft skills” of how to deal with people, especially customers, and understanding the sales process. For me it was a pretty easy transition because I had some aptitude and I really had a passion for evangelizing the technology and helping others. If someone wanted to make that change, they would benefit from training and practice on communicating effectively, dealing with difficult people, presentation skills, influence skills, etc.

CG: With regards to the EDA industry, how much further ahead of the curve does the software end up being? For instance, is EDA working on software necessary to define the 13 nm node currently?

HTAG: As you know, the industry is never at a single point. Rather, there is a spectrum of design nodes being used with some small percentage at the most advanced nodes. Most EDA tools are being developed to address these new nodes, often in partnership with the semiconductor manufacturers developing the process node or the semiconductor designers planning to use them. The big EDA companies are really the only ones, for the most part, that have the resources to do this joint development. Whatever is the newest node being developed, some EDA company is probably involved.

CG: You have written about the nature of the industry and how there being few players affecting the nature of the system. What kinds of limitations do you see in the industry due to the economies of scale (TSMC dominance, for instance)?

HTAG: Consolidation is a fact in any industry and a good thing in EDA. Think of it as natural selection whereby the good ideas get gobbled up and live on with more funding (and the innovators are rewarded); the bad ideas die out. Most small EDA companies would want to be bought out as their “exit”. At the same time, there are some “lifestyle companies” also in EDA where the founders are happy just making a good living developing their tools and selling them without having to “sell out” to a larger company. For all these small companies, the cost of sales is a key factor because they cannot afford to have a larger world-wide sales direct force as the larger EDA companies have. That’s where technologies like Xuropa come into play, that enable these smaller companies to do more with less and be global without hiring a global sales force.

CG: What drives the requirements placed upon new technology in the EDA space? How are the products developed? Are there a lot of interactions with specific big name designers (i.e. Intel) or does it shade more to the manufacturers (TSMC)?

HTAG: In fact, a handful of key customers usually drive the requirements, especially for small companies. When I was at Synopsys, Intel’s needs was the driver for a number of years. Basically, the larger the customer, the greater the clout. Other customers factor in, but not as much. The most advanced physical design capabilities of the tools are often a collaboration between the EDA company and the semiconductor manufacturers (e.g. TSMC) and the also the designers (e.g. Qualcomm). Increasingly, EDA tools are focusing on the higher-levels and you are seeing partnerships with software companies, e.g. Cadence partnering with Wind River.

CG: A good chunk of chip design is written and validated in code. This contrasts with much more low level design decisions in the past. In your opinion how has this changed the industry and has this been a good or bad thing? Where will this go in the future, specifically for analog?

HTAG: Being a digital designer and not an analog designer, it’s all written in code. Obviously, the productivity is much higher with the higher level of abstraction and the tools are able to optimize the design much better and faster than someone by hand. So it’s all good.

For analog, I am not as tied in but I know that similar attempts are being tried; they use the idea that analog circuits can be optimized based on a set of constraints. I think this is a good thing as long as the design works.  Digital is easy in that regard, just meet timing and retain functionality and it’s pretty much correct. For analog there is so much more (jitter, noise margin, performance across process variation, CMRR, phase margin, etc, etc). I think it will be a while before analog designers trust optimization tools.

CG:It seems that the EDA industry has a strong showing of bloggers as compared to system level board engineers or even chip designers. What kinds of benefits have you seen in your own industry from having a network of bloggers and what about EDA promotes having so many people write about it?

HTAG: I think blogging is just one form of communication and since EDA people are already communicators (with their customers), they have felt more comfortable blogging than design engineers. Many of the EDA bloggers are in marketing types of positions at their companies or are independent consultants like me, so the objective is to start a conversation with customers that would be difficult to have in other ways. A result is that this builds credibility for themselves that then accrues to their company. I think there has also been a ton of sharing and learning due to these blogs and that has benefited the entire industry. On a personal level, I know so many more people due to the blog and that network is of great value.

CG: How has your career changed since moving back out of the EDA space and into consulting? What kind of work have you been doing lately?  How has your experience helped you in consulting?

HTAG: It is interesting to have been on the EDA side and then move back into the design side. Whenever I communicate with an EDA company, whether a presentation or a tool evaluation or any conversation, I can easily put myself in their shoes and know where they are coming from. On the one hand, I can spot clearly manipulative practices such as spreading FUD (fear, uncertainty, and doubt) about a competitor and I can read between the lines to gain insights that others would miss. On the other hand, I also understand the legitimate reasons that EDA companies make certain decisions, such as limiting the length of tool evaluations, qualifying an opportunity, etc.

Most recently I’ve been working on some new technology development at a new process node. It’s been interesting because I’ve been able to dig deeper into how digital libraries are developed, characterized, and tested and I’ve also learned a lot more about the mixed-signal and analog world and also the semiconductor process.

Many thanks to Harry for taking the time to answer some questions about his industry and how he views the electronics world. If you have any questions, please leave them in the comments or pop over to Harry’s main site and leave a comment there.

I’ve been going over my personal finances lately. I’ve decided that I would like to increase my wealth (shocker, I’m sure). I’ve always been a bit of a cheapskate and I’ve cut back more thanks to the recession. And so I need to go in the other direction. And why not? Making more is just as effective as spending less on the road to wealth.

So how do I make money?

I’ve never really thought about that before. I guess there are the conventional routes:

1. Ask for more money at my current job — We’re in a recession, remember? Try again.
2. Get a new job — I could, but I like my current job and there are a lot of hidden costs with changing jobs. My move from Austin was pricey, and that was with help from my current employer. Not to mention I would have to win out over the many other qualified people out there who are currently employed. No thanks.
3. Win the lottery — Ah yes, the illogical man’s backup plan. This wasn’t serious, I’m just trying to illustrate how little I’ve thought of making more money for myself in the past.

Wasn’t that a fun exercise? I’m not saying that’s all there is, I’m saying that’s all that came to mind before I really started thinking about it. So what other options are there?

Well, I’m sure at least one or two of you have noticed that I run a website. I could pretend that I could make money on here, selling links and putting up ads for people, but I just don’t think it will work; plus I usually hate how that stuff looks on websites. Aside from the fact that you really can’t make money with a blog, I’m not even sure I would want to. If you focus all your efforts on your one endeavor (such as writing), you lose the spice that makes your perspective so unique. Why else would an online comic artist go back to school for physics? (duh, to get good jokes about nerds!) I’d prefer to write AND continue working with analog electronics every day to be able to use skills I learn from one in the other.

Then there’s consulting. Ah, the money that can be made from consulting, so they say (you know…”they”). The thing is, I really don’t have that much experience yet nor do I have the contacts necessary (the most important part, so I hear). And this whole model is still dependent on others giving you a salary of sorts (albeit with more independence). While this is a possibility in the future, I just don’t see this as a possibility yet. (FYI: I also group “freelancing” in with this category. Freelancing is just consulting for a much lower price in my opinion).

Well why not make something? Selling a product has probably never been easier. The supply chain is set up, you can get prototypes up quickly and cheaply and there is a whole region of the world just waiting for you to send ideas their way that they can manufacture. The problem is, I said I want to make money, not spend it. And spend you will if you ever try to launch a product in any capacity. There’s always the homemade versions of electronics, such as kit manufactures and hobbyist board houses, but they’ve got those models down pat and I don’t have a lot of interest. So as of now, I’m counting the “product” idea out as well.

I wrote this post because I wanted to point out that there may be lots of ways to make money, but I’m stuck in a mode where I am dependent on others to give me a salary. That’s a dangerous position and one that will limit your earning potential over the life of your career. I’ve stated that one of my long term goals is to start my own company, but I’m thinking that I should perhaps start in sooner than later. That way I can get the mistakes out of the way early and decide if it’s a hobby or an actual money making endeavor. The main thing holding me back is that I have zero clue as to what I would do.

What about you? Have you broken out of the conventional model of going to work every day and earning a steady paycheck? I’m on the beginning steps of a long journey that could take many directions and having one or two people wave at me from down the path might make me feel a little better about thinking about finally leaving home.
