From the Vitis IDE, you can modify an
existing RTL kernel by selecting it from the
folder of an application project where it is in use. Right-click the XO file in the
Project Explorer view, and
select RTL Kernel Wizard. The Vitis IDE attempts to open the Vivado project for the selected RTL kernel.
A dialog box opens displaying two options to edit an existing RTL kernel. Selecting Edit Existing Kernel Contents re-opens the Vivado Project, letting you modify and regenerate the kernel contents. Selecting Re-customize Existing Kernel Interfaces opens the RTL Kernel wizard. Options other than the Kernel Name can be modified, and the previous Vivado project is replaced.
