Intellitech's Eclipse(TM) Family of Products is a complete Solution for Design Debug, In-system Device Configuration and Automated Test Program Development for complex PCBs and Systems.  The Eclipse Family provides design and test engineers with a comprehensive set of tools that they can use to create, validate and apply 1149.1 (JTAG) based system configuration and test suites.  All tests can be passed to SystemBIST for embedded test, to Teradyne ICT or to Intellitech manufacturing systems.  The Eclipse family has an extensive line of ultra fast hardware and integrated software options for 1149.1 (JTAG) test and configuration.
JTAG software

The Eclipse Family is a comprehensive test solution that reduces product development costs, speeds time-to-market and improves product quality. Eclipse products enable companies to develop and execute manufacturing tests and perform in-system device programming and configuration using the IEEE 1149.1 test infrastructure.

If you can read a schematic, you can use Eclipse JTAG Test Software

IEEE 1149.1 is an industry standard test protocol that sometimes is incorrectly referred to as JTAG after the original European Joint Test Action Group (JTAG).  Today's 1149.1 technology uses boundary-scan cells on device IO pins to provide virtual access to key nets and pins within a printed circuit board. This enables what is called "ATPG" or automatic test pattern generation.  The ATPG is used to quickly generate tests for a PCB to check the IC-to-IC interconnects.  With Eclipse, the pattern sets are known to be 'deterministic' which is a fancy word meaning that the test patterns generated have a pre-determined fault coverage on the PCB and have a pre-determined diagnostic to the IC pin.  This should be contrasted to 'functional test' which is non-deterministic, the fault coverage cannot be mathematically determined with functional test and the diagnostics are not isolated to the pin.

     "Placing pads for test based on physical access is no longer an option for us; it increases PCB layout time and decreases routing efficiency.  Intellitech's boundary-scan technology allows us to continue to get high digital test fault coverage without test pads."

The automated PCB interconnect testing in Eclipse is the fastest and most cost effective way to develop tests for PCBs with high digital device content.  It eliminates the need for manual test development of IC-to-IC connections and eliminates adding test points late in the PCB design cycle. These IEEE 1149.1 tests are applied using cost-effective hardware and software.  PCBs that have a high digital content that can be tested and configured through 1149.1 may benefit from using the Eclipse Scan Executive manufacturing environment.  If a PCB has long digital test times (including programming FPGAs, CPLDs and FLASH) relative to the analog test times, cost savings can be realized by performing the tests seperate from ICT.  

Eclipse Flow Supports Test Reuse throughout the Entire Product Life Cycle

IEEE 1149.1 test and device configuration data is created, debugged and validated in the lab during product ' bring-up'. Tests created with the Eclipse Test Development Environment are portable directly to the Scan Executive Manufacturing Test Station for execution in a production environment. The Eclipse Test Development environment is also the platform for creating embed-able 'images' for on-board self-test.  This enables the same high coverage tests used in manufacturing to stay with the product when the product is shipped to customers or next level system integrators.  The Eclipse Test Development Environment can be used in the field to apply FLASH program updates or re-configure FPGA and CPLD devices.

JTAG for Debug

Design Debug and Bring-up

The Eclipse Test Development Environment automatically creates tests that are used to bring up new products in the lab. Failures can be quickly debugged using software tools such as the Eclipse Timing Diagram Analyzer and the Schematic Logic Probe.

JTAG for Test

Manufacturing Test

The Scan ExecutiveTM Manufacturing Test Station is used to apply the same IEEE 1149.1 tests that were developed and used in the lab in a high-volume manufacturing environment without requiring additional development.

JTAG for re-configuration

Field Service

The Eclipse Test Development Environment is used at a customer site or in a repair depot to debug failures and update and re-configure existing products.
