Acculogic Boundary Scan Solutions
IEEE 1149.1, also known as JTAG or Boundary Scan, was introduced in 1990.
This standard endeavors to solve test and diagnostic problems arising from loss
of physical access caused by the increasing use of high pin count and BGA devices,
multi-layer PCBs, and densely packed circuit board assemblies.
The standard outlines predefined protocols for testing and diagnosing manufacturing faults.
It also provides a means for On-Board programming of non-volatile memory devices such as Flash,
or In-System programming of devices like PLDs and CPLDs.
Terotest can provide customers with Acculogic's comprehensive line of PC-based hardware
and software tools specially designed for testing of electronic devices, together with boards and systems
using the IEEE1149.1 and IEEE1149.6 standards. These tools can be effectively used
in the entire product life cycle, starting with design verification and validation and
continuing into pilot production and manufacturing.
Acculogic provides best-in-class Boundary Scan Test (BST) tools for automated test
and on board programming application. Acculogic's powerful BST systems are modular
and expandable; they are designed to fit any application, environment and budget.
Boundary Scan Systems
Acculogic Boundary Scan Test (BST) suite is the fastest on the market, with 2 - 10 times the
throughput of any comparable system. The Acculogic BST provides superior test coverage, accuracy,
repeatability and transportability.
The Acculogic BST systems are offered in either Development or Run time configuration.
Development systems are designed for the user to prepare and validate the Boundary Scan
application. Run time systems are offered at significantly lower cost, for use in
production or repair depots, utilizing the programs developed by the engineering department.
Acculogic Boundary Scan Controllers
Acculogic Boundary Scan controllers share a common set of powerful and patented capabilities
that places them ahead of the competitors. These unique features facilitate:
- Adaptive clocking which supports cables up to approximately 15 metres in length
- Proprietary 32-bit Boundary Scan controller
- Non-stop data transmission
- High speed data transmission ~ 25 Mega Bits/second
