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?

Hello,


You can promote critical warnings to errors, this works for both Pro and Standard edition: https://www.intel.com/content/www/us/en/docs/programmable/683463/22-1/promoting-critical-warnings-to-errors.html


As far as I know you cannot suppress errors to warnings.


You can suppress messages too: https://www.intel.com/content/www/us/en/docs/programmable/683463/22-1/suppressing-message-display.html
