Multi-driven nets -> how to report ?

Hi All,

How is it possible to report the multi-driven nets in the design? Should these nets appear in the synthesis log?

Thank you!

    Hello,


    Multi-driven nets are not allowed in VHDL/Verilog HDL/SystemVerilog at all, you will receive below error during Synthesis and this will effectively stop the compilation, there won't be any reports because of that.


    Error (10028): Can't resolve multiple constant drivers for net


    So, if you don't receive this error then there is no multi-driven nets in your RTL code.

    Is there a way to define the severity for the messages (user-defined severity)? I mean re-define an error message as a warning and warning as an error?
