JTAG Visualiser update adds features for faster debug

JTAG Technologies is excited to announce the latest version of its acclaimed Visualiser graphical viewing tool for board (PCB) layouts and schematics. Allowing users to assess fault coverage data and pin-point production test faults in a snap.

Wide-ranging CAD support

With its wide range of CAD (EDA) tool import filters Visualiser is the number one choice for professional boundary-scan development and test engineers. Users can import schematic data direct from Mentor (Pads, DxDesigner, Capture) Cadence Altium and Zuken tools as well as board layout information in ODB++ and a dozen other vendor specific formats.

JTAG Maps

Introduced in this version of Visualiser the new Maps feature offers a basic test-accessibility view by a simple click of the mouse. The view can easily be fine-tuned by adding just a few key component descriptions to a look up table. What’s more using customisable colours to indicate test coverage levels or access types, a colour-coded schematic can be displayed or printed. Once the design has been optimised for boundary-scan test coverage and committed to layout, final application development can begin in the JTAG ProVision developer tool.

Additional new features

Visualise on (Test) FailWhen  running a test sequence or during test debug within ProVision it is now possible to view all failing circuit nets on a schematic view, a layout view or both – automatically. This feature is ideal for small-scale production systems where the test operator is also responsible for fault diagnosis and rework. 

Locate Next – during fault-finding the ‘locate next’ feature allows the user to track the course of a net connection through the layers of a PCB layout or the sheets of a schematic.

Multiple Colour Themes – users can now define multiple colour themes for distinguishing different net classifications e.g. for percentage fault coverage in schematics or fault nets in layouts to aid in debug and repair

View through layers – a highlighted fault net, perhaps as a result of a detected board connection fault, can now be viewed along its entire path and as it changes course through the board (pcb) layers.

Add notes – A note can be added anywhere at a fixed position on the schematic or layout. Ideal for conveying additional information about test processes or passing design details back and forth between users.

Peter van den Eijnden, MD comments: “These impressive enhancements to Visualiser come as a result of our commitments to customer liaison and also our work with various 3rd parties such as the EDA vendors.”

ATE Integration: Simple and effective improvement of test coverage

Clients need to improve the overall test coverage of their assembled boards. It’s easy. Clients can simply combine their JTAG Technologies boundary-scan tools with todays’ existing automatic test equipment (ATE). JTAG works with any vendor of in-circuit testers (ICT), flying probes (FPT) or functional testers (FT).

ATE integration is completely trouble free and merely involves adapting execution software to operate in the specific ATE environment. In many cases we at JTAG develop dedicated, customised versions of the boundary-scan controllers or pods. This simplifies mechanical integration and preserves signal integrity.

Our experts will discuss the level of integration variation according to your needs.
