how to simulate .bdf files in ModelSim-Altera

--- Quote Start ---

Hi,

I am new to Altera QuartusII,

I am trying to simulate a block design file in ModelSim.

I have generated a HDL file from the design and are able to simulate it and view some of the signals.

My problem is that the design uses a BUSMUX mega function, and I am not able to find how to include it in the simulation. All output from the MUX are always "XXXX...X"

Has any one any hints on how to preform a simulation on block design files?

Hi,

did you have a look into your generated designfile ? Is the BUSMUX function implemented as blackbox ?

Kind regards
