Multi-function JTAG board tester fits into ECT fixtures

Date: 03/09/2016
JTAG technologies collaborated with Everett Charles technologies (ECT), which is known for PCB testing and interface components. They have came up with integration of JT5705/FXT multi-function JTAG tester into the small linear series of cassette –based re-configurable equipment.

The JT5705/FXT is a compact single-board test system that supports measurement of analog and digital parameters, digital I/O, boundary-scan testing ( via two TAPs) and also in-system device programming. Latest JTAG software incorporates multiple controller support that allows the linking of multiple units to create a identical system of increased channel counts. JT5705/FXT meets the standards of Automatic Test Equipment industry.

Most of the electronics designs contains programmable logic, micro-controllers ,SOC etc. however due to mixed signal nature of these designs, it is more preferred to have mix of test signals to test these designs. The JT5705/FXT will provide these features.

ECT' cassette is a swappable interface module to provide access to the Unit Under Test (UUT) through spring probes/ nails to link the resource with the equipment-tester to the UUT. By using cassettes different boards can be tested on the same hardware to save cost. Customization of FPGA Kernel allows users to develop their own digital I/O options. Internet protocols can be implemented in FPGA and can be accessed via JTAG technologies. CoreCommander FPGA product implements a translator interface that allows JTAG hardware to control embedded IP cores via a variety of bus interfaces (e.g. Wishbone Avalon etc.).

JTAG supporting compatible TAPs with programming limit (JT5705) unit has extensive I/O capability(64 channels). Multiple JT5705s can be linked and synchronized to provide higher TAP and IO channel counts.

Peter van den Eijnden, MD of JTAG Technologies comments ‘Industrial controls/automation and automotive electronics are just two examples where we expect to see a high demand for this type of product. A great many ECUs require an analog/sensor stimulus which registers back to a microprocessor where the values can be checked using boundary-scan or JTAG emulative test methods - as supported by JTAG Technologies CoreCommander tools.’
