Hi All,
How to get the info of the IR length for non-xilinx devices which are present in the xilinx jtag chain. i need to use chipscope for probing one of the xilinx fpga. hence i need the IR lengths of all the devices in the jtag chain(there are a couple of non-xilinx devices in the jtag chain).
You can usually find it in the datasheet of the components (in the jtag section).
If you can't find it there you need to open their jtag file and look at it.
I can't remember well it because It's about 2 years I don't took a Xilinx (and I'm happy about it)
