Faster debug tool to draw productronica visitors
The latest version of its Visualizer graphical viewing tool for board (PCB) layouts and schematics will be showcased by JTAG Technologies at productronica in Munich (November 14-17). It allows users to assess fault coverage data and pin-point production test faults in a snap.
Offering a wide range of EDA tool import filters 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
In this version of Visualizer the 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.
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.
Among additional features is Visualise on (Test) Fail. When 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.
During fault-finding a ‘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 enable users to 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.
Add notes enables a note to 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.
