Discover Corelis Tools
ScanExpress™ Boundary-Scan Test Products
Corelis ScanExpress Intelligent Boundary-Scan line of products
gives you all of the capabilities you need to quickly generate a
high fault coverage board test procedure and run it at low cost.
In fact, you can save even more by using the Blackhawk
XDS560-class JTAG controller you may already have to execute the
tests. Based on the IEEE standard 1149.1 (JTAG boundary-scan),
ScanExpress locates faults on printed circuit boards with
structural (e.g., shorts and opens) problems as an alternative
or complement to other, more expensive test tools you may be
currently using. You can also use ScanExpress device programming
tools to save costs with its in-system programming capability.
In addition, ScanExpress software can be a valuable aid during
the board development phase. As described in the
Dead Board presentation, ScanExpress can help you isolate
and debug board-level problems even when the board is not able
to boot its full functionality. To summarize the major Corelis
Boundary-scan Test Pattern Generator with built-in
wizard. ScanExpressTPG automatically generates test
patterns that enable testing of boundary-scan chain
integrity, PCB interconnects, buswires, memories,
transparent devices, pullup/pulldown resistors and
test execution software including a test sequencer,
Truth Table Display (TTD) diagnostics, and
In-System-Programming (ISP) support for flash and CPLDs/FPGAs.
It provides comprehensive testing of boundary-scan chain
infrastructure, interconnects, buswires, clusters,
memories, and FIFOs.

and CPLD/FPGA devices via Boundary-Scan, direct I2C,
and direct SPI.
interactive debugger software, an excellent tool for
engineers doing debug during prototype design
verification and testing. Valuable for BSDL file
verification to silicon.

that isolates interconnects faults to the net and pin
level including bridging faults. Eliminates tedious
truth table diagnosis and confusing interaction caused
by multiple faults.

ScanExpress JTAG Embedded Test (JET) Products
JET Supported Texas Instruments DSPs
ScanExpress JET works with
the Blackhawk XDS560 family of JTAG emulators to support
many popular TI DSPs. Before Code Composer is used to
develop code for the TI DSP, JET can be used to verify
the functionality of the board. ScanExpress JET
automatically generates real-time functional tests for
RAM and Flash and custom real-time embedded tests can be
easily created using the simple JET scripting language.
The real-time embedded tests are executed on the target
in internal SRAM, ensuring that problems with external
RAM (SDRAM, DDR, DDR2, etc.) will be properly detected.
The generated JET tests are compatible with ScanExpress
Runner and can be combined with boundary-scan tests to
create a test plan which not only tests the structural
integrity of the board, but also verifies the functional

For board configurations which have a TI DSP TAP connector and a
separate TAP connector for other boundary-scan devices, a
Expander can be used to connect to both TAPs using the one
Blackhawk JTAG Emulator. The Corelis TAP Expander can support up to 4 TAPs (1 TI DSP TAP and 3 additional TAPs).

ScanExpress JET (short for JTAG Embedded Test) is an innovative new
product that lets you run board-level functional tests at full processor
speed. By using your TI DSP or MCU’s existing JTAG port and your
Blackhawk XDS560-class JTAG controller, you can easily create, download,
and execute functional tests on memories and other circuitry hooked up
to your on-board processor. ScanExpress JET lets you create tests that
isolate specific areas of operation, including hard-to-detect signal
JET for at-speed functional JTAG EmbeddedTest (JET) of
processor-based boards. JET includes automatic
generation of memory tests, a scripting language for
creating and modifying tests, and device-specific
library routines for initializing and controlling a
range of processors.
