ScanExpress JET Advanced Diagnostics
At-Speed, Non-Intrusive Functional Test | JTAG Embedded Test Solutions
ScanExpress™ JET Advanced Diagnostics for BGA DDR Memory Testing for Automotive
ScanExpress JET Advanced Diagnostics adds additional diagnostic resolution to ScanExpress JET memory tests with fully-automated analysis. Functional test results are diagnosed down to the net-and-pin level, even on BGA components.
The precise diagnostics are ideal for safety-critical testing of ECU systems during development, production, deployment, and repair. Processor-specific memory tests include multiple memory standards including DDR, GDDR, and more.
ScanExpress JET Advanced Diagnostics integrates with the Corelis ScanExpress suite of software, including ScanExpress Runner for test execution and ScanExpress Viewer for PCB fault visualization.
- Improved fault coverage by combining boundary-scan and JET at-speed test with pin-and-net level diagnostics
- Fault information is presented in a clear, concise format
- Detailed diagnostics go beyond standard functional tests
- Spend less time on fault detection enabling faster prototype debug and releases
- Quickly translates JTAG Embedded Test (JET) functional diagnostics to net-and-pin level
- Clear identification of memory interface faults, including atspeed, timing-critical faults
- Precise fault characterization including short, open, and bridging faults, even under BGA components
- Seamless integration with ScanExpress JET and ScanExpress Runner for boundary-scan and embedded instrument test at the ECU-level
- Compatible with ScanExpress Viewer for fault visualization
- Combine with JTAG-accessible MBIST integration for better ISO 26262 and ASIL requirements testing

ScanExpress JET “13 point” Benefit
Corelis ScanExpress JET represents a major step forward for automatic circuit board testing. The JTAG Embedded Test (JET) method extends coverage beyond popular boundary-scan techniques to virtually every signal of the UUT that is accessible by on-board CPU(s). This includes most of the remaining non-scannable, analog and I/O port resources.
Here is a list of some important JET Benefits:
- JET augments UUT structural test coverage with functional tests when UUT includes CPU device(s) with JTAG debug/emulation port(s).
- JET automatically generates functional at-speed tests for memories and flash devices, saving months of coding, tedious UUT tests debugging and significantly reducing the overall tests development costs. Intuitive GUI guides the user through a logical sequence of test preparation steps, followed by automatic generation of functional test steps from start to finish.
- JET functionally tests components at-speed using embedded tests that are downloaded via JTAG into CPU cache memory or RAM. This increases test reliability and helps you diagnose failures, especially when the board does not boot.
