DDR4 support in XJTAG

We have been starting to see questions about support for DDR4 SDRAM devices, which are gradually becoming available. We have published a guide to using JTAG to test DDR4 memory on the XJTAG website. It contains a link to slides used at a recent presentation on the subject. Support for DDR4 devices will be coming soon [...]

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 could only represent a single static JTAG chain. With our new functionality, multiple JTAG chain variations can be defined, set up and run within a single XJTAG project in a single test run. […]

Driving differential pins in XJEase

A few people have asked us how to deal with differential pins when writing XJEase tests. They see them change value on an oscilloscope during the Connection Test, but aren’t sure how to deal with them explicitly in .xje files. […]
