How can I get mux information?

Jump to solution

Excuse me, I'd like to know how I can get mux information during the synthesis. After synthsis, I can only get lut information, and it seems like all the muxes were completely sliced into luts. Our inputs are .c or .v files, and I'd like to get some messages about anything related to mux such as mux-tagged luts. This seems a easy question but I really don't know how to do it as a new user of vivado.

You can search for MUX primitives in the generated netlist after opening the synthesized design. If you are not able to see any MUXs in the netlist then there is a possibility that the logic was pushed into LUTs.

 

For EX: show_objects -name search_MUX [get_cells -hierarchical -filter { PRIMITIVE_TYPE == MUXFX.others.MUXF7 } ] command will list all the MUXF7 cells in the netlist.

 

As I can understand from your post, you are working on HLS design. To check the MUX related logic in VIvado, open the elaborated design and check the MUX logic and use the cell name to search the synthesized design.

 

Thanks,
