- In the Explorer
view, select the top-level system project to create a new PL project to add to
it. Right-click on the system project and select the Add Hw Kernel Project command, as shown in the following
- This displays the Hw Kernel Project
Details page of the New Vitis IDE Project wizard as shown
in the following figure.
Make sure the project is assigned to the existing system project, which also contains your AI Engine graph project. Specify the HW Kernel project name. Click Finish to proceed.
- This creates the PL kernel project and adds it to the hierarchy
of the top-level system project. Next you must add the source code for your
kernel. In the Explorer view, select the src folder of the PL kernel and click the Import Sources command () to open the dialog box shown in the following figure.
Browse to and select the necessary source files for your PL kernel. Click Finish to import the source files to your HW kernel project.
- With the source files added to the project, you must define the HW function to place into the PL region. In the Project Editor window, select the Add Hardware Function command () and specify the name of the function to implement in the PL region.
After creating the AI Engine graph project, which also creates the top-level system project, and a hw-link project, you can create PL kernel projects to add your system. You need to create a PL application project and add it to your system project using the following process.
With the PL kernel project created and the HW function defined, you can build the kernel project for the Emulation-SW, Emulation-HW, or Hardware targets. You can build these targets directly in the PL kernel project or as part of building the top-level system project. The top-level project uses an incremental build approach that recognizes the state of the sub-projects and only rebuilds projects that need to be updated.
