COMMAND NAME:

        IMPORT

USAGE:
        IMPORT [ filename | 'design_name']
        IMPORT [ filename | 'design_name'] <time>
        IMPORT [ filename | 'design_name'] <time1> <time2>

        This command is used to import waveform activity from a file
        <filename>  OR the simulation output for the design_name.
        Note that design_name must be quoted. Otherwise, it is treated
        as a file name.  This command will recall waveform activity
        that is explicitly saved using the WRITE command OR the output
        of the simulation for a design.
	
        If no time value is supplied, the entire waveform activity will
        be imported.

        If one time value is supplied, the time will becomes the start
        time for importing waveform activity and all waveform will be
        imported to the end.

        If two time values are supplied, the waveform will be imported
        only in this period of time.
