PROBLEM
JTAG or boundary scan was developed to address the "loss
of physical access" problems that occur as a result of implementing
new packaging technologies.
Since its standardization (IEEE 1149.1) boundary scan usage
(also known as JTAG) has expanded and evolved into something more
like a communications protocol running within an electronic system.
In this way, it is similar to the Internet -- which allows you
to access all kinds of information. Boundary scan allows you to
access all kinds of design and test structures.
Those structures help you:
- Debug and test boards
- Program devices
- Diagnosis hardware problems
SOLUTIONS
ASSET JTAG boundary-scan tools help solve interconnect test
problems, and enable CPLD/FPGA Programming
and Flash Programming.
Boundary scan delivers this functionality because it can be used
to access the "internals" of a:
- Device -- to run Built-In Self-Test (BIST)
- Board -- to verify proper assembly
- System -- to help configure a system
So JTAG gives you the ability to test a:
- Device and access internal scan
- Board and program devices
- System and verify assembly of boards
to daughter cards, multichip modules (MCMs) and to other boards
on the backplane
If you would like to get started implementing boundary scan using
PC-based tools, our customers find success combining the following
four elements:
