Tips for setting up an XJLink-PF40 pin mapping
With the release of the XJLink-PF40 and XJTAG 4.1, setting up your pin mapping might have just got a bit more complicated. The XJLink-PF40 supports twice as many TAPs (8) and has twice as many I/O pins (40) as the XJLink2 so there can be more work involved in setup. Luckily, XJDeveloper 4.1 contains some [...]
Built-in Test Reset Sequences for devices with nTRST pins
XJTAG 4.1 can automatically generate test reset sequences for many more hardware designs than previous versions. Previously, if a JTAG device had an nTRST pin that needed resetting between tests, you had to manually create a sequence with a waveform like the following: […]
Multi-sourcing Device Configurations
New in version 4.1, XJTAG has support for multi-sourcing test device configurations. This post will explain how to define multiple possible configurations for your test devices. A follow-up post will compare XJTAG’s Variants, Revisions and Multi-sourcing features and explain which is best to use in different scenarios. […]
