Simulating Bidirectional bus in MAX+PLUS II

how to simulate bidirectional pins

How can I simulate a bidirectional (BIDIR) bus in waveform editor( for example data[15..0] )?
I insert two group nodes, one with I/O type Input (e.g data[15..0]) and other with I/O type Output ( same as preveius). But after simulation the two group nodes become same.
If I must use another technique in Graphic editor for common bidirectional bus that transfers output data when the write signal is high and brings input data when read signal is high, please notify me.
Thanks a lot.

maybe modelsim is more suitable for simulation bidirection signal.

If u r using Max + 11 for simulating bidirectional pins, they will produce an input pin and an output pin of the same name.. Maybe u should try with Modelsim for the simulation of bidirectional pins.
