About IEEE1149.1 JTAG TestJTAGTest is invaluable tool for all embedded designers, production houses and service companies. JTAGTest helps you with PCB debugging, prototyping, testing and repairing. The device pin signals or internal signals can be monitored in real-time without interfering with normal device operation, or you can actively change pin states. All this is possible using an IEEE 1149.1 (JTAG) boundary-scan.

Wide range of functions
JTAGTest has easy to use interface. It was originally used as a in-house tool for a few years, before it went public.
Automatic JTAG Scan chain detection is provided, you don't have to specify parts in a chain by hand.
JTAGTest provides visualised boundary scan debugging which allows to view and control pin/ball/pad states. Furthermore, everything can be recorded, which turns JTAGTest into a logic analyzer.
Visualised PCB debug
JTAGTest has intuitive, very easy to use interface. Devices in a chain are automatically displayed as icons.
Visualised boundary scan: device pin, pad or BGA ball states can be displayed as a listing or graphical chip view. Logic levels are displayed using colors.
Boundary scan mode also allows easy probing and controlling each by selecting desired state from a list. You can also record waveform for further analysis. JTAGTest can be turned into logic analyzer!
3rd party CAD/CAE application support
JTAGTest supports SVF programming, you can use it to program various devices (tested on Xilinx ISE, Altera Quartus and Lattice ispLever)
We provide ULP script to export netlist from Cadsoft Eagle
Xilinx *.UCF, Altera *.PIN or Lattice *.LCT files can be loaded into JTAGTest.
JTAGTest is following standards
JTAGTest and ViaTAP JTAG-USB Interface are IEEE 1149.1 compliant
Industry-standard BSDL, HSDL and SVF files are fully supported, including various extensions
Hardware supports more than 20 widely used JTAG pinouts
JTAGTest provides ECMA-262 compatible scripting language which can be used for extended debugging, bulk programming, testing, or production.
ViaTAP JTAG-USB Interface
Our ViaTAP JTAG-USB Inteface supports more than 20 widely used JTAG pinouts, so you can smoothly use it for you existing designs or evaluation boards.
The interface is fully compliant with IEEE 1149.1 and we have tested it with almost all common chips available on market.
You can use ViaTAP not just with JTAGTest, but also our other programs!
