ScanExpress Software Components for Testing Electronic Assemblies using Boundary-Scan
ScanExpress TPG™ is an intelligent test pattern generator that enhances the process of boundary-scan automation at an exceptional level of ease of use. ScanExpress TPG automatically generates test patterns that facilitate pin-level fault detection and isolation of all boundary-scan testable nets on a printed circuit board (PCB). ScanExpress TPG also creates test vectors to detect faults on pins of non-JTAG components such as clusters and memories that are accessible by IEEE-1149.1 compatible devices.
ScanExpress JET™ represents state-of-the-art 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 DFT™ Analyzer is able to accurately calculate the test coverage of boards and systems that include a mix of both boundary-scan and non-boundary-scan devices. The software additionally helps development engineers detect low coverage areas on their designs allowing them to make decisions on increasing fault coverage before the board is sent for layout.
Test Execution System
ScanExpress Runner™ provides a runtime executive environment that is friendly for design, production, and field service. ScanExpress Runner allows users to execute a test sequence or individual test steps based on test patterns generated with ScanExpress TPG and/or ScanExpress JET. To identify failures - if any - a truth table diagnostic display is generated for further inspection.
ScanExpress Runner Gang™ is the workhorse software piece to perform parallel gang testing and In-System Programming of CPLDs and Flash devices. This solution is fully concurrent and allows simultaneous testing of multiple boards using a single PC and a single operator. ScanExpress Runner Gang addresses high-throughput boundary-scan applications including high-volume production.
ScanExpress Viewer™ is a powerful graphical fault identification system that helps to isolate the source and location of faults encountered during boundary-scan test of printed circuit board assemblies. The device and pin location capabilities provide test operators the immediate board location of the faulty pin or net.
ScanExpress ADO™ is an add-on option for the ScanExpress Runner and ScanExpress Runner Gang execution environments. The Advanced Diagnostics Option automates test vector analysis by intelligently deciphering standard truth table diagnostic information and presenting specific fault information to the user in a detailed verbose format.
ScanExpress Merge™ makes system-level boundary-scan test development a snap by automatically combining multiple target assemblies into a single boundary-scan compatible target system. The tool provides automatic handling for each board netlist, scan-chain, and interconnect information.
ScanExpress JTAG Debugger™ provides a simple, stand-alone environment for complete pin control over any boundary-scan device. The interactive graphical user interface lets users mimic the functionality of a logic analyzer by observing all boundary-scan controllable inputs while also providing the capability to drive output pins to specific logic states. The software can be used to quickly apply patterns to specific areas of a board giving immediate feedback when faults are detected.
Boundary-Scan In-System Programming (ISP) Tools
ScanExpress JTAG Programmer™ is a universal in-circuit programming tool that can program and verify Flash memories, serial EEPROMs, CPLDs, FPGAs, and other programmable logic devices. Programming methods include JTAG, I2C, SPI, and Target Assisted. The extensive device library includes chip manufacturers such as Altera, Cypress, Micron, Spansion, Intel, Microchip, ST Microelectronics, Texas Instruments, Xilinx, and many more.
The ScanExpress Flash Generator™ creates a Board File, which is used to provide ScanExpress Programmer (or other compatible applications) with the necessary information to program a given target board configuration. ScanExpress Flash Generator can be used as a standalone utility or as a module integrated with the ScanExpress TPG environment.
Corelis ScanExpress applications have been updated with the latest features, enhancements, and device support.
ScanExpress Runner now includes an asynchronous API for integration with third party applications. The asynchronous execution functions allow applications to integrate ScanExpress Runner functionality without having to wait for execution to finish—applications can now begin execution and then poll to determine current status or abort the current execution.
The new functions are:
AsyncAbort() Aborts asynchronous Test Plan execution.
AsyncGetStatus() Retrieves the current status and completion percentage of asynchronous Test Plan execution.
AsyncRunTestPlan() Runs the currently loaded Test Plan asynchronously, returning immediately.
ScanExpress Runner Diagnostic & Logging Improvements
ScanExpress Runner now includes full test plan and test step path information in the test log file for improved traceability. Additionally, flash manufacturer and device ID information will now be included in diagnostics and test logs when Device ID tests pass. Finally, we’ve improved JAM/STAPL diagnostics to include additional checksum data when available.
ScanExpress Runner Gang USB-1149.1/4E
ScanExpress Runner Gang can now utilize USB-1149.1/4E and QuadTAP/CFM hardware for concurrent test execution. Gang (concurrent) tests on up to 4 TAPs can now be run on the benchtop with USB-1149.1/4E hardware or integrated into Teradyne testers with the QuadTAP/CFM and expander cards.
ScanExpress JET CPU Support & Improvements
ScanExpress JET supports many microcontrollers, FPGAs, and SoCs, e.g. Infineon's Aurix, Nvidia's Tegra K1, NXP's CorIQ P2, Xilinx Zynq, and Mobileye's EyeQ3 devices. Starting with version 9.4 ScanExpress JET supports Marvell OCTEON III CN7200 Multi-Core MIPS64 Processors and Texas Instruments TMS320C6748 DSP Processors. Each new processor support package includes base RAM and NOR flash tests and programming support. Please contact Corelis Sales for pricing and availability. Additionally, Ethernet loopback tests are now included for NXP i.MX6 Applications Processors.
Corelis ScanExpress 9.4 is now available free for customers under maintenance. Please, inquire for more information.
