Corelis ScanExpress JET Whitepaper

Download Whitepaper on Enhancing Boundary-Scan with JTAG Embedded Test

Corelis’ ScanExpress JET represents a major step forward for automatic circuit board testing. The JTAG Embedded Test method extends coverage beyond popular boundary-scan techniques to virtually every signal of the UUT that is accessible by the on-board CPU(s).  This includes most of the remaining non-scannable, analog, and I/O port resources. As a bonus, it employs full-speed functionality verification without modifications to the circuit, its onboard firmware, or the test fixture.

Article Includes:
