Strength

Hello everybody, 

 

I have a question regarding the use of the strength of the signals(highz, small, medium, weak, large, pull, strong, supply) 

As far as I understand if 2 signals with 2 different strengths are driven through a wire, through the wire will circulate only the signal which is the strongest. 

Is there a possibility to assign to the wire signals with different strength but to make the signal with the smallest strength go through the wire? 

 

Thanks

First signal strength can only be used in simulation. The synthesizer will not accept two drivers on the same signal, even if one is weak and the other strong. 

Second in VHDL you could create your own resolved type that would transmit the weakest signal instead of the strongest, but I have a hard time finding any practical applications.
