As are all Seica systems, the Valid Line is based on the powerful
VIVA software environment. CAD data can be directly imported
to create a comprehensive data base for test generation,
validation and diagnostics. The board schematic, layout and
nomenclature are dynamically linked and controllable by the
user.
Test steps and source code are also
synchronized during execution to ease debug.
VIVA also includes a number of tools specifically
oriented for functional test generation such as a
simulator for digital test, a Virtual Channel
encoder for 1149.2 cluster test, and a powerful,
hardware-independent test language (NVL). All
of these features enable the test engineer to
completely focus on achieving the desired
results, rather than on resolving limitations of the
software environment.
The complete software architecture of the Valid
Line is based around the Component Object
Model (COM) technology, which enables the
creation of re-usable software components, easily
linkable, to favour a powerful open system
environment. Thus, the Valid Line systems can be
delivered to operate in the environment which is
familiar to the customer, such as N.I. TestStand or
Agilent VEE. Through the use of COM
technology, either VIVA or N.I.
TestStand communicate directly with object
codes, passing events and data at test execution
time. Instrumentation and test sequences can be readily operated under COTS tools, such as Microsoft Visual C++ or
Visual Basic, N.I. LabWindows/CVI or LabView, and others.
Besides full access to the Virtual Instrument tools offered with COTS instruments, the Valid Line offers QuickTest, a
global Virtual Instrument environment, to access all Seica hardware. QuickTest allows the user to graphically interact in
real time’ with the tester hardware and the UUT to create test sequences that can be prepared off-line (hardware
emulation) or directly executed and viewed.
Results can be stored and become part of the overall test program. QuickTest allows technicians to use any part of the
powerful and complex platform of the Valid Line with the same ease that they use any familiar lab instrument, without
requiring knowledge of the system and time-consuming data base preparation.
POWERFUL TEST GENERATION,
VALIDATION, RUN-TIME ENVIRONMENT
COMPREHENSIVE
DIAGNOSTIC TOOLS
Level III test requirements demand precise fault
location in order to speed up operations, reduce
the cost of PCB repair and eliminate scrap. The
Valid Line fully supports guided probe
operations for digital and analog type of circuits
as well as fault dictionary based techniques.
Digital guided probe at speed can be driven by
simulated, or directly learned data. A fault
dictionary can also be used on line, in
conjunction with the guided probe, or off line. In
addition to the proprietary simulation tools, the
Valid Line can also directly post-process LASAR
simulation results.
Analog diagnostics extend the guided probe
algorithms to analog clusters, with analog DC
and AC measurements and automatic trace back
and isolation of the source of the fault.
Valid line
With the Valid Line you are not locked into a single system
configuration. The base system is offered on a vertical
architecture, combining a prestigious looking line with a
high degree of ergonomics essential for operator comfort.
The system includes an ample work/desk area and a flat,
adjustable LCD monitor. The main diagnostic instruments
(manual measurement probes, oscilloscopes, transducers)
are strategically located above the test adapter section.
The System bay can be supplied in the traditional Seica
extra-size, or with the standard 19” dimensions.
If the main utilisation of the system is with bed-of-nails
fixtures, a horizontal work-bench version is offered. In
both cases, expansions are easily accommodated by
adding a second or third bay to host additional
instrumentation.
Optimum scalability of the system is ensured by means of plug-in expansions and upgrades directly in the field.
A version of the Valid, hosted on the ATEC-MT series, is supplied through EADS Test and Services, in partnership with
Seica.
LOW COST MODULAR, COST EFFECTIVE
SYSTEM CONFIGURATION AND ERGONOMICS
Since its creation in 1986, Seica has gained recognition as a trusted supplier of test
equipment and services for defence and aerospace electronics manufacturers and
depots worldwide. All over the world Seica products and services help ensure cost-
controlled Legacy Replacement of obsolete ATE, mission readiness of critical
modules, manufacturing and logistics preparation for future advanced electronics.
Seica’s hardware, software and service approach has made the Valid Line the natural
choice to replace obsolete ATE at Thales, Dassault Aviation, Galileo Avionica, GE,
offering smooth migration and long-term support of existing TPS’s, and state-of-the-
art tools for future developments on avionics such as the Eurofighter Typhoon or the
Rafale.
Continuous technical innovation is driven concurrently by the large presence of
Seica’s solutions on the commercial market, such as the automotive industry, where
Seica has a prominent position, and Seica’s unique philosophy of using a “common”
hardware and software core for all of its products benefits all Seica customers.
The addition of new test technology for one industry is immediately available to
others: one example is Boundary Scan 1149.2 test generation and diagnostics,
which is now present in the Seica platform as a natural extension of functional test
executed on clusters combining physical and virtual access, and not only as a
separate, external tool.
Combining test experience and direct research and development investment with an
open hardware and software approach, Seica offers unconstrained but
comprehensive solutions to its customers. As an example of the appreciation of the
quality of Seica test environment, VIVA has been chosen by EADS North America to
provide comprehensive test development and execution software for their Talon
Instruments™ family of T964™ high-performance digital test instruments.
DECADES OF DEFENCE AND AEROSPACE TEST
EXPERIENCE
THE VALID LINE
Designed around a common hardware and software architecture, the Valid Line is offered in
several different configurations to address for the customer; ergonomics, test strategy, and
deployment from board depot to full production level test.
VALIDATE AND VALID PLUS BOARD TEST SYSTEMS
FOR LEVEL III
VALIDATE
ValidATE is the architectural implementation of the Valid Line for Level III
(Board Test) applications. The system bay measures 60x96x182 cm and hosts
28 card cage slots using a VIP Test Backplane for a capacity up to 768 digital
(or 384 full hybrids) high performance functional channels. Channel capacity
can be doubled by adding a second VIP Backplane; a larger version of the
system, hosting a 40 slot VIP Backplane(s) is also available. The system is
offered with a standard choice of two types of receivers, the Seica traditional
pin-bed and the ODU, which has a wide variety of extensions for ancillary
connections of high frequency signals, coax, fiber-optics, pneumatic, etc.
Custom receivers to accommodate specific requirements are also readily
engineered. The system can be expanded to accommodate one or two
additional bays for external instrumentation.
VALIDATE PLUS
ValidATE Plus is electrically the same as the ValidATE System. The
ergonomics are changed to best suit the requirements of combined in-circuit
and functional test, when a bed-of-nails fixture is more appropriate. Together
with the ability to thoroughly verify the functionality of digital, analog and
mixed-mode circuitry, the ValidATE Plus can extend its application to power-
off, structural and power-on in-circuit techniques. The system combines
best-in class solutions for board testing to meet performance, capacity and
fault location capabilities. The system takes advantage of all techniques to
reduce test generation cost, without affecting fault coverage or throughput.
Power-off structural tests, using both junction and capacitive techniques, are
first used to isolate simple manufacturing faults. Power-on in-circuit tests, both
analog and digital, including extensions to IEEE 1149 techniques, are then
deployed through the non-multiplexed hybrid channels of the system. Where
required, fast On Board Programming (OBP) operations can be performed.
Finally, the full power of functional test can certify operation of the UUT.
The ValidATE Plus base configuration is a single horizontal bay that
accommodates the system’s power distribution, UUT power supplies and the
test backplane to host various types of channel cards and instrumentation. The
ValidATE Plus is an ideal ergonomic solution to be used with bed-of-nails
fixtures, offering the operator full access control to the UUT, control panel, oscilloscope and system’s PC, as well as a
comfortable area for documentation, schematic and tools. The system can be expanded to accommodate one or two
additional bays for external instrumentation. Standard or custom fixtures are pneumatically (or alternatively vacuum) engaged
into a robust, high performance receiver, granting access through the signal bus of the test backplane to all resources of the
system.
