Smart
Engineering Tools designs and manufactures highly specialized tools
for the automotive industry, including the Netway tool that provides
real-time emulation and analysis for multiplex automotive networks
with digital, analog and PWM signals capabilities. The Netway can
be connected to a PC using serial or/and USB interfaces and operates
in stand-alone mode. It handles all network channels simultaneously,
thereby supporting gateway functionality. The device is delivered
with application software.

A
special Netway script language allows users to configure the tool
for variety of tasks, such as:
- gateway
functionality and message conversion between different network
protocols,
- real-time
network emulation and analysis,
- on-board
data recorder and playback functions,
- custom-controlled
bus interface,
- stand-alone
module to simulate "missing nodeĦħ or "rest of vehicle",
- end-of-line
testing for manufacturing of multiplex modules, and
- data
logging and recording with dynamic filtering.
Network
messages are logged based on a network configuration file, user-defined
filters, and user program flow. In addition to these more complex
functions, the Netway is also designed for such simple tasks as
monitoring and filtering network traffic, broadcasting outbound
network messages and generating output signals. The Netway is housed
in a single box that supports integration of optional daughter boards
supporting a number of automotive protocols: multiple CAN channels,
J1850 Ford and GM/DC, K-line (ISO9141, LIN), J1708, ACP and other
custom protocols. A variety of handled protocols - combined with
8 digital outputs and 8 analog/digital inputs and PWM input/output
capabilities - renders Netway a powerful tool for automotive network
analysis and diagnosis.
The
Netway is capable of converting information from one network or
signal to another in real-time with worst-case one millisecond resolution.
This feature allows users to utilize the tool in number of vehicle
fleet applications where it is used as a translator from one network
to another, such as from CAN to J1850. The Netway has been used
by a wide range of customers ¨Cincluding such major automotive OEMs
as GM, Ford, DaimlerChrysler, Toyota, Mazda, Nissan, Delphi, Visteon,
Bosch, Continental-Teves and Denso - since 1997. The original Netway
device is based on the PHYTEC miniMODUL-167
Single Board Computer subassembly. Due to increasing demands for
microprocessor throughput, including an analysis showing that future
Netway users would require at least a 40 MIPS-capable processor,
a new generation of Netway devices was developed based the phyCORE-XC161.
Upgrading
to a XC161-based solution allowed overall improvement throughput
of the system about tenfold, while decreasing the total cost and
complexity of the system mainly due to additional on-chip resources
available on the XC161, such as on-chip CAN, MAC, I2C, Flash, JTAG
and peripheral event controllers.
