ScanExpress Boundary-Scan Test Products

The 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 Debugging a 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 ScanExpress products:

ScanExpress Runner – Test Program Execution

Boundary-scan 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.

Visual PCB and Faults Viewer/Locator using overlaid CAD and digital PCB photo files.

You can learn much more about the ScanExpress JTAG/boundary-scan line from the ScanExpress Overview datasheet or by visiting the ScanExpress web page.

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 operation.

For board configurations which have a TI DSP TAP connector and a separate TAP connector for other boundary-scan devices, a Corelis TAP 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 – JTAG Embedded Test

jet icon - Texas Instruments CustomersScanExpress JET™ represents a quantum leap in automatic circuit board testing by extending boundary-scan structural test coverage to virtually every signal on the board that is accessible by an on-board CPU. ScanExpress JET utilizes proprietary “JTAG Embedded Test” (JET) technology, which uses a processor’s JTAG debug port to download and control native processor code to perform at-speed functional testing of the UUT.

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 integrity issues.
