The HLS compilation mode provides access to numerous features for the
development, optimization, analysis, and export of Vitis kernels (.xo) or Vivado IP
(.xci) files. The HLS mode can be reached by using the following command:
v++ -c --mode hls -h [options] <input_files...>The HLS compilation options should be entered into a configuration file for
use with the v++ command using the --config option, as described in Configuration Files. The HLS options should be placed under a section head
of [HLS] in the config file. For example the following
config file specifies the part, the source file, the test bench files, and the flow
target. Notice that part is not specified under the [HLS] header because this is a general option for the
v++ compiler.
part=xcvu11p-flga2577-1-e
[hls]
clock=8
flow_target=vitis
syn.file=../../src/dct.cpp
syn.top=dct
tb.file=../../src/out.golden.dat
tb.file=../../src/in.dat
tb.file=../../src/dct_test.cpp
tb.file=../../src/dct_coeff_table.txt

clock_uncertainty=15%
Tip: To use the HLS config options on the
v++ command line you can simply begin the command
name with --hls. For instance, to specify the
flow_target from the command line use --hls.flow_target. The HLS mode command options are described in the following sections.
