ChipScope Pro Analyzer - How can I initialize a JTAG chain with non-Xilinx devices that are not JTAG compliant

Description

One device of my JTAG chain is a non-Xilinx part which has a Bypass instruction different than 0xF...F (or 0b1111...11). In other words, the Bypass instruction contains zeros, which means the device is not JTAG compliant.

How can I use ChipScope Pro Analyzer, initialize the JTAG chain and detect ChipScope cores with a JTAG chain with non-Xilinx devices that are not JTAG compliant?

Solution

It will not be possible to use ChipScope Pro Analyzer if a non JTAG complaint device is present in the JTAG chain targeted. At the minute it is not possible to add a 3rd party BSDL file to ChipScope Pro analyzer. This is a known limitation of the tool that is planned to be enhanced in further software version even though there is no fix scheduled for a specific build for the time being.
