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 [...]
Layout Viewer Visualisation
Having lots of information is great, but sometimes the most difficult thing is displaying that data in a meaningful way. We have created two new information overlays for Layout Viewer, allowing you to visualise test coverage statistics or live pin data from Analyser on your board layout. […]
