Support multiple .xo files #138

Dear Authors,

I have used tapa for a while and now I met a problem and wondering if you are convenient to help.

In my project, I have multiple different kernels which need to be called by the host asynchronously. Therefore, I am wondering if it is possible to generate RTL for different kernels from different top files. For example, I want to deploy the 'topcnn1632' 'topfc1601' and 'topbanks' kernels on the u280 board. I have tried the following command but it considers the topfc1601.cpp topbanks.cpp as unrecognized arguments. Could anyone provide any suggestions? Thank you.

rtl: mkdir $(WORK_DIR) tapac \ --work-dir "$(WORK_DIR)" \ -o $(krnl_name).$(platform).hw.xo topcnn1632.cpp topfc1601.cpp topbanks.cpp\ --platform $(platform) \ --top topcnn1632 topfc1601 topbanks \ --work-dir $(krnl_name).$(platform).hw.xo.tapa \ --enable-floorplan \ --floorplan-output "$(WORK_DIR)/$(krnl_name)_floorplan.tcl" \ --connectivity top.ini \ --max-area-limit 1.1 \

Hi @tangyuelm, if you would like to generate multiple kernels that will be called by the host separately, you'll need to generate multiple xo files and link them together using v++ --link kernel1.xo kernel2.xo.

Thank you for the reply. However, I have another concern. If I generate multiple. xo for these kernels separately, will the optimization of Autobridge still benefit the overall floorplan for all the kernels?

Correct, autobridge does not support multiple xo kernels.
