The component of the IBUFG you have declared in the testbench does not precisely match the IBUFG entity. The ports are std_logic and std_ulogic. I've had some problems in the past with this, causing exactly the behavior you see. Whether it's a GHDL thing or a VHDL thing I don't know.

You are right, when I change std_ulogic to std_logic then I got correctly signals.
I hope some notice come in. What is correctly?


This is not nice at the moment.

Subject: [Ghdl-discuss] Simple line simulation

   Hallo,

I have a problem or a bug or what ever. Now I have reduced to the
smallest code.
The reproducer is in the attachment.

In my code I have a simple  connection from input to output.
The amazing is the signal output is correct but the signal o in the
instance is undefined.
The signal o and output are the same but I get different waves??!

René
