Control
The intention of the Internet of Things is to digest and
control these objects in a way that we typically do not,
currently. For consumers, this could mean an Androidapp allowing you to check and adjust the temperature
of your living room without leaving your couch. Or a
wearable fitness device that can perform the same
function, albeit from the trail. Whatever the case, you
have a thing and a way to access it via the Internet.
Measure, Observe and Feedback
This part is diff icult to quanti fy, but in general terms,
the Internet of Things is seen to utilize sensors for the
measurement of environmental phenomena. Some of
these sensors might include: Inductive
Capacitive
Temperature
Humidity
Pressure
Infra-red
Electromagnetic waves
Acoustic
Biological
Gas
Location Orientation
Directional forces
Forms of radiation
Where it differs from standard, engineered practices
for using a sensor (for example, using a temperature
sensor to monitor motor temperature or an infra-red
sensor as part of a limit switch) is that these sensors
are attached to devices and networks that they
typically wouldnt be.
For example:
A capacit ive sensor/sheet attached to a door, to tel l
when a person knocks on it
An acoustic sensor to detect when a dog is barking
Accelerometer on an armband to characterize the
exercise theyre undertaking
Connected
Once youve acquired the information from your
sensors and their associated controls, you must
make it accessible via the Internet. Its not unlike theevolution of the television set with buttons and dials or
the so-called smart televisions we have today, which
can be controlled from your phone. This connectivity
could be from your phone over Short Message Service
(SMS), a local network (WiFi or LAN or CAN) and
even the global internet. Hence the name, Internet of
Things, or by some, Internet of Everything.
Problems to Overcome
The Internet of (Every)Thing(s) has potential problems.
These problems are partly based around: Transport infrastructure of the data collected.
Presentation and storage of the data into tangible,
coherent and relevant information.
Integrity, security and privacy of valuable and
sensitive information from collection through to
presentation.
Transportation
The transport infrastructure, if we consider that all
communications from these devices may move to
an Internet Protocol (IP) based system, will rely onthe ability to navigate IPv4 and IPv6, not taking into
account intermediate communication methods up until
that point. This places expectancy on the devices to
be able to have enough power to use a network stack
at some point in their transmission or transportation.
Currently a lot of systems are utilizing IPv4, of which
the global address space has practically run out.
There is a very slow migration to IPv6 which has a
significantly larger amount of address spaces available.
However, it may come to pass that a translationoccurs between the two and IPv4 is used for the
smaller networks. I would hazard to suggest that it
may not even be required depending on the data
collection mechanism (eg. RFID, bluetooth, etc.)

Presentation/Storage
If were suggesting an Internet of Things type of world,
where potentially every object can feed back details
of its existence, then that is a lot of information thatneeds to be stored somewhere. Consider the example
may report on their status along the entire route of
their global journey. That data requires a transportation
mechanism thats accessible almost everywhere, and all
that information must be stored somewhere. Decisions
would have to be made as to how valuable the data
about to be stored is; what it is intended to be used for;
and how it would be displayed to the interested parties.
Integrity, Security and PrivacyThese are important factors when dealing with
should also always be a consideration. Lets lead with
an example:
An elderly lady is wearing a watch that monitors the
status of her health, electrocardiography (ECG) signals
and mobility. It is customized to her and contains a
the lady when shes either traveling, or in the home and
the watch tries to connect and report that she hasntmoved for a long while. The watch attempts to report
the current state to a system that can determine if the
ECG signals are low, whether this is bad, whether
someone should check on
her and so on.
There are a few areas
that could be raised for
concern with such
a scenario:
The information reported by the watch is incorrect
(or the watch is actually not being worn) and the
actions taken to check on the lady are incorrect.
An occurrence in which the watch was unable toreport to the system, or the wrong watch reported
to the system.
Someone has intercepted the signal the watch was
trying to communicate, discovers that something
has happened to the lady and takes advantage of
the situation in a nefarious way.
The device (s) involved in the system are no longer
maintained because of succession to the product
(end of life), or perhaps the company has gone
under. Because it was not open-source, there is no
one left to maintain the system and the issue goesunreported.
Corruption occurs in the system or the system
does not perform its calculations properly. Perhaps
it does not have redundancy to handle the
information thrown at it during maintenance and the
situation is ignored or delayed.
These are the very concerns attendant with any existing
system; they are not unique to Internet of Things-based
applications. It is the scale that stands to vary.
Should We Do This?
Yes, in my opinion, and whether we should or not
the technology is here. Technology in general stands
to gain from our interest in Internet of Things-based
applications, as designers will be required to optimize
for portability, low power, integrity and security of
information. So, what will you bring to the party?

The Internet of Things
Drives New Design Approach
By Mark Toth, Business Development Manager, CadSoftComputer. Originally published in The PCB Magazine
The most common question asked of electronic
product developers today is how do you do more
with less? How do you incorporate newer, faster
technologies in smaller packages to take advantage
of new products and architectures that provide more
functionality and power efficiency, all on time and
under budget? Is it possible to retool processes
without negatively impacting designer productivity?
Can advanced techniques and current best practicesbe made available at the designers fingertips during
development without leaving the design environment?
Increased consumerization, of electronics and a
convergence of various elements of functionality, due
in part to the IoT (Internet of Things), is putting intense
economic pressure not only on time to market, but on
cost of development as well. Add to that increased
competition in the electronics industry and continued
globalization, and were seeing increased investments
in tools, training, new best practices and increasingopenness to collaboration.
To il lustrate the continued globalization...
The EDA Consortium (www.EDAC.org)in its
most recent report showed Printed Circuit
Board and Multi-Chip Module revenue of
$148.3 mil lion, a YoY increase of 5.2 percent
compared to the same quarter in 2012. The
four-quarter moving average for PCB & MCM,
however, increased 10.0 percent. This iscompared to overall industry revenue which
increased only 3.8 percent YoY for the same
quarter reported, but dropped almost
1 percent in sequential quarters. The four-
quarters moving average, which compares
the most recent four quarters to the prior four
quarters, increased by only 5.3 percent.
Not surprising, a geographic trend for the
design tool industry shows revenue for
increased to $431.9 mil lion in the most
recent quarter reported, an increase of 18
percent compared to the same quarter of the
prior year. The four-quarter moving average
increased 14.4 percent.
The opportunity costs for electronic productdevelopment are exponential, but there are major
pitfalls as well. A simple rule of thumb in management
consulting practices states that, on average, companies
six months late. One could easily argue the penalties
market, which has now far exceeded the $200B mark.
Design cycle time plays a big part in determining a
product launch schedule, and the PCB layout part of
this process is often called upon to make up for earlydesign phase schedule slips. In todays competitive
climate, finding ways to reduce design cycle times is
a priority for all engineers. Of chief concern for many
companies is that as PCB design becomes more and
more complex, engineers need to have cost effective
tools that reduce time-to-market. Another potential
challenge is the fact that companies have design
teams dispersed all over the world.
Given all those factors, its easy to see how
completing a product launch within the specifiedtime frame can be daunting. To address all of these
challenges, companies need tools that can leverage
their existing resources (both human and computer),
allow interoperability, have a gentle learning curve and
can offer extensions that link other time-intensive parts
of the design cycle or supply chain.

In a recent industry survey conducted by CadSoft
Computer to commemorate the 25th anniversary of
EAGLE for PCB prototyping, designers from 42 different
countries weighed in on future requirements, as well asemerging trends in electronic product development.
Some of the results were surprising:
64% of respondents think development boards are
reducing the need for custom PCB design.
Almost half (46%) are developing with Open Source
Hardware platforms.
Eighty-three percent agree peer-to-peer communities
are important, while 25% believe they are essential
Other results were not unexpected: The majority of designers put functionality before cost
when buying design tools, with 60% of respondents
rating functionality as an extremely important factor
A design tool should offer a gentle learning curve
Design tools should:
Allow multiple designers to lay out a single project
Have a plug-and-play model for tasks that are
intensive to increase productivity
Allow designers to collaborate with each other in real-
time from anywhere in the world
While it is true that more and more design projects
are being started with off the shelf development kits
and boards instead of designing a PCB from scratch,
engineers will often need to design an interface board(such as a shield, cape, expansion, daughter card,
etc.). This is a market where many PCB tool companies,
As more and more open source hardware platforms are
some large, global silicon suppliers are now offering such
low cost open source kits to the Maker and hobbyist in
hopes of increasing demand for their technologies. TIs
Launchpad series is just one example.
What about peer-to-peer, social media, designing in
the Cloud and other forms of collaboration are these
trends fuelling designer productivity?
Although somewhere between novel idea and trend, a
few considerations need to be addressed before the
cloud is deemed mainstream for electronics design.
These include risk and compliance (such as data
cloud sooner). From a business standpoint, it is more

more PCB designers to make it a more sustainable
model. Determining factors for a design application
to harness the power of the cloud are tied to obvious
cost, security and so on. If your design application is
not performance-intensive, or the cloud does not lower
your development costs or improve productivity, it
might not make sense just yet.
Other online resources and communities, however, have
common design elements and identify new technologies
engineering community with more than 200,000members, enables developers to connect with like-
minded peers to gain design inspiration or obtain expert
answers and opinions. One of its most active forums
is hosted by the CadSoft EAGLE user community. In
addition to answers and advice, element14 contains a
free database of CAD libraries, which are searchable
by component supplier, thus enhancing designer
productivity and cost to develop.
Another trend that continues to evolve in the PCB design
industry is the tighter forms of integration between
product into production, electrical CAD (ECAD) and
Mechanical CAD (MCAD) data must be merged. A virtual
3D representation of the PCB geometry within MCAD
tools allows Mechanical Engineers to quickly design
product housings as well as other mechanical features
that fully utilize the available 3D real estate. MCAD
features such as cross-section views and interference
issues when prototypes are built.
Generating a virtual 3D representation
of PCB geometry within MCAD tools has
historically been a time consuming task.
IDF (Intermediate Data Format) has been
around for 20+ years, but in the ear lier days
of IDF, the labor involved to create 3D PCB
representations was time consuming and
costly, states Keith Richman, President of
Simplified Solutions. In 2014, many tools
are available to help expedite the 3D PCB
process. Manufacturers and onl ine servicesnow provide 3D STEP Models that can
help populate a 3D PCB. In addition, some
solutions contain integrated 3D component
librar ies that allow the 3D geometry task
to be completed in just hours. 3D printer
technology can then be utilized to generate
a geometric 3D representation of PCB
geometry prior to the more expensive
manufacture of PCB prototypes.

17 The Internet of Things Drives New Design Approach
Speaking of component libraries...The amount
of information needed on thousands of different
components threatens to overwhelm even the most
organised professional. Challenges for board designerswith this sort of technology is dealing with and
creating the complex shapes needed to implement
the components. Engineers comment regularly I am
spending too much precious product development
time creating footprints or in other parts of library
management. This is a very important issue which
greatly impacts designer productivity. You cant be
designing a custom part for each component you
want to add to your circuit. While some 3rd party tools
come with many libraries already, tens of thousands
more are available online or in design portals such asthe element14 community from manufacturers and user
shared libraries.. Building a custom library can take over
20 minutes per part for a small quantity from scratch,
can rely upon a rich pool of information validated by an
active community. Within complex devices if the design is
open, users can specify the parts through an integrated
search on a parts database with an online distributor
or electronics supplier. This allows electronic design
with parametric search to choose the right components,and have access to a huge amount of technical
information regarding the components themselves

available from within the design environment without
having to jump between several websites. This virtual
integration of the design chain not only enhances design
quality and designer productivity, but it reduces risks
associated with misidentifying a critical component or
selecting a part that is obsolete or out of stock.
Jeremy Blum, Open Hardware Designer
and Hardware Engineer at Google [x] points
out. .... as designs continue to get more
and more complex, following best practices
becomes more and more important. For novice
designers, its easy to encounter a myriad of
potential design problems that may or may not
be caught by traditional DFM checks. Some ofthe things to look for when preparing a PCB
for production are problems that are only fully
understood by designers who have been doing
PCB CAD for many years. Luckily, as open
source designs become more common place,
and as more and more professional designers
join communities like element14, it becomes
easier and easier for new designers to get
help and t ips from industry veterans. A truly
community-driven design platform makes the
barriers to entry lower than ever before.
Once engineers have homed in on the bill of materials

manufacturability as it is about functionality, quality
and performance. Designers are packing more and
more components onto smaller and smaller boards into
smaller enclosures, placing unprecedented demands on
design, analysis and simulation tools.
Many are resorting to exotic and/or
aluminium-clad PCB materials, via in pad or
HDI features, blind/buried via technology to

While there are a plethora of commercial products

there are relatively few that are low cost and yet lend

complex design can be accelerated while keeping the
upfront design costs low.
Despite the increasing levels of semiconductor
integration and readily available systems-on-chips
for many applications, not to mention the increasing
availability of highly-featured development boards
which can be used out-of-the-box, electronics product
development still relies heavily on custom PCB design in
many cases. Even for one-off developments the humblePCB still performs an important role; its a physical
ingredient to pull any electronics system together.
