Build and Simulate in the Vitis IDE - 2023.2 English

From the left pane in the Vitis IDE, select the AI Engine Component, and expand to locate and select the aiecompiler.cfg file to open the compiler configuration settings.

Select the XLOpt settings and under the Kernel optimization setting, select the 0 - None from the drop-down. This gives greater visibility during the AI Engine debug.

Right-click the [aiengine] domain project, select C/C++ Build Settings, choose Miscellaneous -> Optimization -> from the drop down choose No Optimizations(xlopt=0). This option helps IDE debugging capability by disabling any kernel optimizations.

Now, in the Flow navigator window, select the Build option under AIE SIMULATOR/HARDWARE. This builds the AI Engine component for AIE Simulation target. Once the build completes, you see the Compilation Complete and Build Finished Successfully messages in the console and a green tick mark as highlighted below.

In the Flow navigator window, under AIE SIMULATION/HARDWARE, select the Run option. If there is no existing launch configuration, you need to create one by clicking Create Configuration -> New Launch Configuration -> AIESim.

You can change the Launch Config Name, and click the Run button to start the simulation for the AIE simulation target. When the simulation completes, the following output in the console is displayed.

Right-click the [aiengine] domain project, and select the Run As → Launch AIE Emulator option to start the simulation for the aiesimulation target. When the simulation completes, the following output in the console is displayed:

The aiesimulator output files from design are located at ${PROJECT}/Emulation-AIE/aiesimulator_output/data, and the golden output data is located at 09-debug-walkthrough/reference_output/. Verify the output files ${PROJECT}/Emulation-AIE/aiesimulator_output/data/output_upscale.txt and ${PROJECT}/Emulation-AIE/aiesimulator_output/data/output_data_shuffle.txt against the golden files 09-debug-walkthrough/reference_output/upscale.txt and 09-debug-walkthrough/reference_output/data_shuffle.txt to ensure that the design’s I/O functionalities are correct. The Vitis IDE supports compare with the feature to compare two files.

• Add the golden data to the ${PROJECT}/data/ by right clicking the data/ directory in the [aiengine] domain project, and select Import sources.

• Highlight the two files to be compared.

• Right-click one of highlighted files, and select compare with > each other with transformation. Click the Predefined filters icon (as shown below). Enable the Remove timestamp checkmark, and click OK twice. Selecting each other with transformation is required because the AI Engine simulation inserts a timestamp for each output data. For example, compare ${PROJECT}/data/golden_upscale.txt and ${PROJECT}/Emulation-AIE/data/output_upscale.txt. .
