Categorising Transistors in XJDeveloper
Transistors are one of the things we get asked about quite a bit: “How should I categorise the transistors in my project?” […]
Introducing Dynamic Chains
‘Dynamic Chains’ is a term we’ve coined to describe a test system that has the ability to drive more that 1 JTAG chain configuration. This may be possible if it has multiple chains driven by different TMS or TCK pins, or a single chain that has multiple JTAG device variations (for example using a Scan Bridge). Before v3.3, XJTAG projects [...]
Wiring a bed of nails test jig for JTAG
When using JTAG with a Device Under Test (DUT) connected to a bed-of-nails test fixture, often little attention is paid to the way the JTAG signals are wired. This article (published in SMT magazine last year) gives a helpful explanation of why it is important to get this right, and gives tips for best practice.
Using XJTAG without netlists
XJTAG is a great system for board designers and manufacturers, but people looking to repair boards often do not have netlists for those boards – something that until now has been essential to start an XJDeveloper project. […]
Automatic suggestion of JTAG chains
To help get your tests up and running more quickly and easily, version 2.7 of XJDeveloper has a new feature which can make suggestions for the JTAG chains in your project. […]
