same wire to 2 bidir io pins

Hi, I have a bidir pin ( MDIO) it is connected to a wire and then the wire connects to inside the sub modules. How can I make this wire connect to another bidir pin? If I try quartus...

I don't believe that it is possible to directly connect one bidir pin to another bidir without issues. There are ways that you can cheat this in special cases, but generally does not work well. (expect glitching on the output).

Is it possible to put down an actual wire external to the FPGA to suit your purpose? (more information on your application may be helpful)
