Vitisあれこれ

ビルドフローを再確認
まずはリソースの準備

• vadd.cpp，host.cpp，host.hppを用意
• design.cfgを用意

platform=xilinx_u50_gen3x16_xdma_201920_3
debug=1
profile_kernel=data:all:all:all

[connectivity]
nk=vadd:1:vadd_1
sp=vadd_1.in1:HBM[0]
sp=vadd_1.in2:HBM[1]
sp=vadd_1.out:HBM[2]

• xrt.iniを用意

[Debug]
profile=true
timeline_trace=true
data_transfer_trace=coarse # <coarse|fine|off>

でビルド

source /tools/Xilinx/Vitis/2019.2/settings64.sh
source /opt/xilinx/xrt/setup.sh
export platform=/opt/xilinx/platforms/xilinx_u50_gen3x16_xdma_201920_3/xilinx_u50_gen3x16_xdma_201920_3.xpfm
g++ -I$XILINX_XRT/include \
    -I$XILNX_VIVADO/include \
    -Wall -O0 -g -std=c++11 \
    host.cpp -o host \
    -L$XILINX_XRT/lib -lOpenCL -lpthread -lrt -lstdc++
v++ -c -t hw --config design.cfg -k vadd -o vadd.xo vadd.cpp
vitis_analyzer vadd.xo.compile_summary
v++ -l -t hw --config design.cfg -o vadd.xclbin vadd.xo
vitis_analyzer vadd.xclbin.link_summary
./host vadd.xclbin
vitis_analyzer vadd.xclbin.run_summary

実行後のサマリを見るとHBMが3つぶらさがってる様子が確認できる．
