Warning message: "Missing drive strength"

Hello

with Quartus 18.0 and a Max10 device I get following I/O assignment warning message:

When I check the Pin Planner I see following default values:

Question:

  • Why this warning message when the default current drive strength is set to its default value?!

 

 

thanks

Quartus is weird: it says you are "missing drive strength" because you didn't explicitly create the assignment yourself to have it written into the .qsf file. What you see is the default and is not written in the .qsf. You can safely ignore this or manually add a drive strength assignment.
