Debug Core Insertion in Non-Project Mode - 2021.2 English

2021.2 English

Debug cores can be inserted in either Project Mode or Non-Project Mode. The following sample Tcl script shows how to create the debug core, set debug core attributes, and connect the debug core probes to the signals in the design being probed. In Non-Project Mode, the insertion of the debug core needs to happen after synthesizing the design, and prior to the opt_design step as shown below.

Important: Debug core insertion is only supported for ILA cores.

The following Tcl script is an example of using the debug core insertion commands in a Non-Project flow.
