Is it possible to write the build script and HLS source files to a directory without having Vitis HLS installed?

Hi,

I am working on developing an online class about machine vision and we want to use hls4ml as a tool to convert ML models to HLS that can be synthesized for a Xilinx FPGA. The program gives students access to a virtual machine with a GPU, but only 36 GB of storage, so we don't have room for Vitis HLS. I am wondering if it is possible to use hls4ml to write the the correct source files and build script to a directory that we can then transfer to a machine that does have Vitis HLS installed and just run a script to tell Vitis to synthesize the model into an IP core.

Thanks.

None of the steps before the hls_model.build() require Vitis HLS to be installed. The hls_model.compile() step creates all the files needed to build the systems, and they can be copied over. There's a tcl script that can be passed directly to vitis_hls afterwards to build the project and synthesize the model.

Great! Thank you for the quick response! I will let you know if I have any other questions.
