JTAG Debug Information File (.jdi) Definition
An ASCII text file in the Extensible Markup Language (XML) format. When the assembler creates a programming file, a JTAG Debugging Information File is also generated, but only when there are instances that use the JTAG interface, such as Signal Tap, in the design. The JTAG Debugging Information file contains data for all such instances compiled in the design for the use by certain tools, such as the In-System Sources and Probes Editor, to obtain their instantiation information. The data includes names of parameters, and input and output ports.
You can use the JTAG Debugging Information File to recreate instances in the In-System Sources and Probes Editor.
