Phase 1: Compile AI Engine application and PL Kernels and Link the System - 2023.2 English

In this lab, all the operations are completed within a terminal. A Makefile contains all the operations for the phases of this lab. Open it in any editor or display it in the terminal using more, less, or cat.

Phase 1 is completed in the following stages:

1. kernels: Build the PL kernels. The output is a number of XO files, which are packaged RTL kernels.

2. aie: Build the AI Engine graph. The output is the file libadf.a, which is the compiled graph with all the PL/AI Engine interfaces.

3. link: Link the AI Engine array design with the PL design. This stage creates the XCLBIN and the XSA files.

There are also optional stages to simulate the AI Engine application using the aiesim target and run_emu to launch hardware emulation that includes all the PL kernels.

In the terminal, type make clean phase1. All the required stages (kernels, aie, and link) are run in the terminal as well as in hardware emulation (package and run_emu).

Check the placement of the AI Engine kernels using an AMD Vitis™ Analyzer and opening the graph.aiecompile_summary file.

Note: The hardware emulation does not launch automatically. Launch it manually:

cd /run/media/mmcblk0p1
./host.exe a.xclbin

At the end of the simulation, the following message is displayed:
