Integrity Test Using x1149 Boundary Scan Analyzer
应用文章
This application note describes in detail what the Keysight x1149 Boundary Scan Analyzer performs during the Integrity test.
In each new x1149 project, the x1149 test program generator will automatically generate a suite of tests called Infrastructure tests that consist of the following:
- Disable test
- Integrity test
- ID Code test
- User Code test
- BReg Length test
The Infrastructure tests check on the fundamental functions of the TAP Register within the Boundary Scan device as well as along the boundary scan chains. This includes the basic functions of the TAP controller (a state machine) in the device, the connectivity of the TAP interface of each device in the chain to the board under test as well as the connectivity to the JTAG interface to the tester.
