Bidir pins together ?

[Altera_Forum]

Hi, 

I'm currently trying to connect two bidir pins together in a schematic with quartus (as you can see on the picture) but, i don't why, i get this error : BIDIR pin "xxx" feeds BIDIR pin "yyy" maybe i should put something between my two bidir ?  but which component because I only need (must have) a wire Thanks in advance

you can't do that. without control logic, should a pin be input or output ?? in which directions should the sinal flow be from left to right or vice versa ? 

you need to control that with an output enable

Each bidir pin must be driven by a tri-state driver.
