Vitis Tutorials: AI Engine (XD100)

2023.2 English

The Makefile is simple. It allows the user to compile for two different targets x86 and hw, visualizes the compiler output in vitis_analyzer, runs an AI Engine or X86 simulation, and visualizes also the output in vitis_analyzer.

Currently, the Makefile does not specify where the DSP Lib includes are located. The first step of this tutorial consists of adding the following lines, on line 27:

#########  Add DSP include files location   #########
DSP_FLAGS := --include=$(DSPLIB_ROOT)/L1/src/aie
DSP_FLAGS += --include=$(DSPLIB_ROOT)/L1/include/aie
DSP_FLAGS += --include=$(DSPLIB_ROOT)/L2/include/aie

Type make aie to run the following command:

aiecompiler -target=hw $(AIE_FLAGS) $(DSP_FLAGS) $(AIE_GRAPH_FILES)

This compiles the design and maps it to the AI Engine Tiles.

Visualizing the compilation results is performed by typing make compviz, which runs the following command:

	vitis_analyzer $(AIE_OUT_DIR)/test.aiecompile_summary

After vitis_analyzer opens, it displays the Summary page, which provides a brief summary of the project.

Vitis Analyzer Summary

Selecting Graph on the navigation bar shows a diagram of the filter implementation. It illustrates the data connectivity points into and out of the graph (128-bit interfaces), and the symmetrical FIR filter kernel being implemented on a single tile with ping-pong buffers on either side of it.
