Hi all, 

in a complete project compilation, I solved all errors and warnings; 

there remains only this:  

 

warning: some pins have incomplete i/o assignments. refer to the i/o assignment warnings report for details 

 

watching on the PIN assignment, I see this on all output PINs: 

 

missing drive strength and slew rate 

 

but the strange thing is that on the slew rate column of the pin report, I see those PINs with the slew rate value of "2(default)", assigned by Quartus by default. 

What can I do to remove this last warning? 

 

Thanks to all

Hello, 

set values of drive strength and slew rate in Assignment Editor, then these assignments will be complete.
