To compile the mm2s, and s2mm PL HLS kernels, use the v++ compiler command which takes in an HLS kernel source and produces an .xo file.
To compile the kernels, run the following command:
make kernels
Or
v++ -c -t sw_emu --platform $PLATFORM_REPO_PATHS/xilinx_vek280_es1_base_202320_1/xilinx_vek280_es1_base_202320_1.xpfm --save-temps -k s2mm pl_kernels/s2mm.cpp -o s2mm.xo
v++ -c -t sw_emu --platform $PLATFORM_REPO_PATHS/xilinx_vek280_es1_base_202320_1/xilinx_vek280_es1_base_202320_1.xpfm --save-temps -k mm2s pl_kernels/mm2s.cpp -o mm2s.xo
Looking at the v++ command line, you will notice several options. The following table describes each option.
| Switch/flag | Description |
|---|---|
-c |
Tells v++ to just compile the kernel. |
-t |
Specifies the compilation target for software emulation. |
--platform/-f |
Specifies the path to an extensible platform. |
-k |
The kernel name. This has to match the function name in the corresponding file defining the kernel. (E.g., For kernel mm2s the function name needs to be mm2s.cpp. |
-o |
The output file must always have the suffix .xo. |
--save-temps/-s |
Saves the generated output process in the _x directory. |
