JTAG Technologies is showcasing, among other products, the new JTAG/boundary-scan hardware interface product compatible with the Virginia Panel (VPC) mass interconnect system. The JT 2147/VPC is a signal conditional module that allows "ideal world" connections from JTAG Technologies PXI and PXIe DataBlasters to the VPC connection system.
Based on the highly-successful QuadPod™ architecture from JTAG Technologies, the JT 2147/VPC has been specifically designed for connection into G20x or G14x 192 pin "QuadraPaddle" connectors and is compatible with the VPC ‘pull thru' system. By integrating the JT 2147/VPC, test system builders will greatly simplify their wiring task and, at the same time, retain the excellent signal integrity assured by the QuadPod's active interface.
The JT2147/VPC features four independent JTAG Test Access Ports (TAPs) along with 16 static DIO channels and 64 dynamic DIOS channels. Each TAP can be programmed to operate through a range of voltage levels to suit various logic families.
Peter van den Eijnden, managing director, comments on this new product, "JTAG Technologies equipment is used world-wide within Mil/Aero and other industries as a component within functional testers. The JT 2147/VPC will greatly simplify the system builder's tasks and enhance the power of their test systems through improved signal conditioning."
JTAG/boundary-scan applications prepared using JTAG Technologies ProVision or "Classic" software tools may be executed on this PXI platform with driver packages that are available for NI LabView, TestStand, and LabWindows alongside Geotest ATEasy and a number of generic language compilers (e.g., .NET framework, C++ and VB). The VPC adapters utilize standard QuadraPaddle connector modules, providing a wide variety of contact types. The connection between the PXI(e) instrument and receiver module is accomplished using either a passive printed circuit board, active signal condition module (as with the JT 2147/VPC) or flex circuit, with each providing optimum connectivity performance while reducing wiring cost.
AutoBuzz, the most exciting addition yet to JTAG's no-netlist-required range of JTAG/boundary-scan test and debug tools-
Autobuzz: Favourite in Mil/Aero Repair and Service Centres
AutoBuzz is an amazing tool that uses a unique "seek and discover" feature to scan completely a compliant design and then perform comparative tests using JTAG/boundary-scan.
With only JTAG scan-chain information plus BSDL models of the JTAG/IEEE std 1149.1 compliant parts (available from manufacturers' web-sites), users of AutoBuzz will be able to connect to their designs via a number of compatible JTAG interface options. AutoBuzz can then be set to gather a complete ‘connectivity map' of any board's boundary-scan to boundary-scan pin connections (where these can be direct or via ‘transparent' devices such as series resistors).
