    In QuartusII, how to covert a *.tdf file to a *.gdf file?

    Re: In QuartusII, how to covert a *.tdf file to a *.gdf file thank you, RTL viewer is work. but the result isn't suitable for anylies the tdf file. for example, the ddf[7..0] are showed in seperated mode:8 ddf; and every member of bus is showed seperated. this leads the figure is tedious.
