these two technologies. Along with the chal-
lenge of engineering data paths that operate
in the microwave spectrum changes in power
delivery has emerged as a major source of
design problems.
ese same ICs that have
billions of transistors o en require several
di erent power supply voltages. Examples are:
1.0V for the core at as much as 100 amperes,
1.5V for the I/O at dozens of amperes, 1.1V for
the phased-locked loops and 1.2V at several
amperes for the memory interface. It is not
uncommon for a PCB design to have more
than a dozen di erent supply rails with some
recent designs having more than 25 di erent
Vdd rails. Successful power delivery system
design is emerging as the most di cult part of
many new designs.
Until recently, much of the electronics indus-
try has relied on PCB fabricators to select
the materials, design the stack-up and calcu-
late the impedances needed on a PCB.

method worked reasonably well before these
semiconductor advances were made. With
current and future designs, how well the
power delivery system performs along with
the quality of the signal paths is intimately
tied to how the PCB stack-up is engineered.
PCB fabricators are not equipped with the
technical skill to account for all the issues that
need to be dealt with when designing the PCB
stack-up. As a result, design and signal integ-
rity engineers must take charge of this part of
the design process.
is requires substantial
new skills on the part of this team.
ese performance advances require a whole
new set of design and fabrication disciplines,
as well as far more knowledge of materials
available with which fabricate PCBs needed
by these advances, not necessary as recently
as the year 2000. Due to the rapid changes in
technology, university courses and text books
have not been able to keep pace, leaving stu-
dents with an information gap that interferes
with their success doing design work on
these new products. Where do engineers and
designers turn for the information necessary
for success with these new design demands?
One place to turn is a seminar being o ered by
a training company located in Silicon Valley
that specializes in this area.

Speeding Edge, whose president, Lee Ritchey,
has been actively participating in designs of
this complexity and shares this knowledge in
three day seminars o ered around the world.
He is recognized as the foremost expert in

SYSGO integrates Kaspersky
Security System into PikeOS
e Kaspersky Security System platform is
a dedicated solution designed to ensure the
safety of information systems that demand
enhanced security. It is available as an embed-
dable OEM component to manufacturers
and vendors of comprehensive IT solutions.
Examples of such solutions include ERP and
electronic document management systems,
smart grids, the Internet of
ings or even
critical infrastructure. At Embedded World,
Kaspersky Lab and SYSGO showcase a secu-
rity solution for safety-critical tasks which
embeds the Kaspersky Security System within
the real-time operating system PikeOS.
R&S: RTE oscilloscopes now with
up to 2 GHz bandwidth
Rohde & Schwarz has expanded its family of
R&S RTE oscilloscopes to include two- and
four-channel models with 1.5 GHz and 2 GHz
bandwidth.
e T&M expert now o ers the
broadest selection of products in this class,

SEGGER adds security feature to
Flasher: Authorized Flashing
SEGGER has developed a new security fea-
ture for its production ash programmer line,
as well as the Flasher Portable: “Authorized
Flashing”. It allows to limit the number of
ash programming cycles thus preventing the
production of unrestricted quantities by third
parties in case of external production.
HCC: MISRA- compliant TCP/IP stack to
include HTTP, SMTP, SNTP/NTP and
SNMP protocols
HCC Embedded has extended its MISRA-
compliant TCP/IP stack to include HTTP,
SMTP, SNTP/NTP, and SNMP protocols. All
come with security options enabling them
to be used with HCC’s veri able TLS and
Encryption Manager. With these additions, the
embedded developer gains access to an exten-
sive range of network protocols, all supplied
with rigorous MISRA-compliance reports and
a full test suite that veri es target functionality.

TI’s MSP430 microcontrollers
IAR Systems introduces its latest product
innovation C-STAT. C-STAT provides pow-
erful static analysis and is now available fully
integrated in the high-performance develop-
ment toolchain IAR Embedded Workbench
for Texas Instruments’ MSP430 MCUs.
LieberLieber Software: cooperation
with Lauterbach
LieberLieber So ware and Lauterbach have
joined forces to create a solution for the opti-
mization and debugging of embedded so -
ware directly on the model in addition to the
source code level.
e solution will be pre-
sented at the Embedded World Conference as
a specially-created demo version available at
both companies’ stands.
Rogue Wave improves developer
productivity with three product releases
Rogue Wave So ware announces updates to
three of its agship products. Rogue Wave reg-
ularly adds new features and functionality to its
growing portfolio of products in order to sup-
port developers as demand increases for higher
quality, more secure so ware - in less time.
ARM and Green Hills: optimised
compiler for Cortex-R5 processor
ARM and Green Hills have collaborated on an
optimised compiler for the ARM Cortex-R5
processor that delivers record-setting auto-
motive performance, enabling the Cortex-R5
processor to meet the needs of the most
challenging automotive applications more
cost-e ectively than any other MCU solution
currently available.
