I want to use a command whose detail i can`t find in hspice manual.

That is
.ac data=dataname
.data dataname par1 par2......

Does it`s first parameter 'par1' mean frequency ,and the command analyzes
the value of par2.... at every frequency given in par1?

regards

Re: about spice

I don't know if this is helpful but in Berkeley spice (and command line Pspice and ISspice) the .AC command is expressed as
.AC LIN <number of points> <start frequency> <stop frequency> or
.AC OCT <number of points> <start frequency> <stop frequency> or
.AC DEC <number of points> <start frequency> <stop frequency>
and the first parameter is the number of points between start frequency and stop frequency as defined by parameters LIN, OCT, DEC. LIN means linear sweep, OCT sweep by octave and the number of points is per octave and DEC means sweep by decade and number of points is per decade. Since all spice versions derive from the Berkeley Spice the commands must be similar.
