Cerritos, CA, March 15, 2007
– Corelis Inc., a leading supplier of high-performance
boundary-scan and JTAG emulation debug tools for
microprocessors, announced today the availability of ScanExpress
JET™, an innovative test tool which combines boundary-scan and
functional test technologies to achieve higher test coverage.
Dubbed JTAG Embedded Test (JET), the software combines common
pin and net level diagnostics using boundary-scan testing with
CPU emulation testing through its JTAG port. This provides
functional test capabilities on designs utilizing JTAG
compatible CPUs to even non-JTAG peripheral components including
analog parts connected within the CPU address and I/O space.
This means that sound structural tests for opens and shorts can
be performed via boundary-scan while at-speed functional testing
can be performed using the CPU to run test programs loaded into
memory. Before loading test programs into on-board memory,
ScanExpress JET is using a proprietary technique to test the
on-board memory at speed without loading any code into this
memory. This means that ScanExpress JET can test and diagnose
faulty boards and systems even when the embedded CPU is not able
to boot and the board self test is not operational.
ScanExpress JET carries existing
boundary-scan testing to the next level. Because no single test
technology offers 100% test coverage, test engineers are
constantly looking at ways to combine the strengths of each test
methodology and maximize the overall testability of their
products.
ScanExpress JET now offers a
feasible way to close the gap between boundary-scan testing and
functional testing. Utilizing a single software and hardware
tool to combine the two technologies reduces test integration
time yet still provides greater test coverage.
Users can access pre-built
functional tests or create functional test scripts from scratch
to test non-standard parts. Furthermore, because ScanExpress JET
seamlessly integrates with existing Corelis hardware, existing
ScanExpressTPG™, and ScanExpress Runner™ customers can add-on
this functionality without having to purchase an additional JTAG
controller to access the embedded CPU. Corelis multi-TAP
controllers can provide emulation and debug capability on one
TAP while connecting the rest of the boundary-scan chain on
separate TAPs. No other test tool currently allows this
configuration. Performing all of the testing from a single JTAG
controller not only reduces cost, but also simplifies the
hardware required for testing and the connection to the product
under test.
"Test technologies have been
grouped into separate classes for years. These technologies are
commonly referred to as manufacturing defect analysis (MDA),
in-circuit test (ICT), and functional test," said Karla May,
Boundary-Scan Product Marketing Manager at Corelis. "Our
customers are looking for ways to bridge the gaps between these
test technologies. ScanExpress JET offers a first step toward
this goal. The addition of ScanExpress JET certainly provides
our customers the means to achieve higher test coverage within
an already mature high performance boundary-scan tools set."
ScanExpress JET takes advantage of
the fact that most of the 32-bit and 64-bit processors have a
built-in JTAG emulation debug port. ScanExpress JET uses the
JTAG debug port to control the CPU and perform functional tests.
Pricing and Availability
ScanExpress JET is available now.
Pricing starts at $17,000.
