Volcano Network Architect from Mentor Graphics Verifies and Improves Network Bandwidth Usage at Mazda

Mentor Graphics Corporation (NASDAQ: MENT) today announced that
Mazda Motor Corporation has chosen the Volcano™ Network Architect
(VNA) software to verify their network bandwidth usage. The VNA is
a tool to design primarily CAN, but also LIN, networks in a vehicle
and facilitate a mathematical way to calculate the worst case
scenario on a CAN bus. Mazda’s use of VNA has enabled significant
improvements in network efficiency and reliability.
Mazda has developed their new generation technology, “SKYACTIV
TECHNOLOGY,” in order to achieve their vision to deliver driving
pleasure as well as outstanding environmental and safety
performance in their vehicles. The CX-5, one of Mazda’s latest
products, features breakthrough SKYACTIV TECHNOLOGY and is now
available to the global market.
Mazda has their unique CAN stack in their vehicle networking
systems and has been using their own, in-house CAN network design
tool. To introduce SKYACTIV TECHNOLOGY, Mazda shifted their
existing tool to the Mentor Graphics® software VNA to insure their
network configuration would work under the worst case conditions.
During the tests that Mazda conducted, several networking issues
were analysed and were able to be improved upon. In particular, by
entering the network data generated from their tools into the VNA,
Mazda was able to analyse their network usage and identify which
messages on the bus caused problems.
The VNA tool has very powerful optimization features to load the
network more than 90 percent of available bandwidth. In Mazda’s
case, their engineers used the analysis from VNA to optimize and
verify that the network bandwidth is utilized to an increased level
but is not overstressed. This procedure increased the network
utilization and significantly reduced the testing requirements and
time. Moreover, what was learned by the VNA tool could then be
applied to new network additions and the VNA flow Mazda implemented
to verify their networks made their networks significantly more
efficient and reliable.
“Mazda changed from our internal tool to Mentor Graphics’ tool
for automotive network design systems. Migrating from an in-house
design environment to Mentor Graphics’ Volcano Network
Architect-based design environment moved smoothly and it reduced
the testing requirements and time significantly,” said Tetsuhiro
Yamashita, staff manager, Vehicle Development Division, Vehicle
System Development Department, Mazda Motor Corporation. “We are
happy to have improved our design quality, as well as our
automotive network reliability.”
“VNA has unparalleled capabilities in enabling design,
implementation and optimization of deterministic communication
systems, leading to profound improvements in efficiency, quality,
and reliability of in-vehicle networking,” said Serge Leef, vice
president and general manager, System Level Engineering Division,
Mentor Graphics. “We are pleased we have been able to provide a
product to Mazda that makes the management and maintenance of their
distributed network solutions more efficient.”
