Show me netlist when you invoke parametric sweep.
Dear Pancho,
The parametric has no problem, it is well working, but I am asking why the simulation fail to present data in grpah if I do the sweep from DC ?

See the image below to better explain,
you see the graph of the ICMR which I want to have, x-axis is the VIC that I sweep from 0 to 3.3.
AV is the gain I should have from AC simulation
Now the first thing I do is to run the DC and AC simulation together, the AC simulation to find the AV, the DC simulation is to sweep the VIC. This setup fails, the simulator is not running AC for every change in the VIC, he only take one value of VIC (the default value which i put to 1.65 V) then he run the AC simulation on it.
in my second setup I only run the AC simulation, but I sweep the VIC by using the parametric sweep, this configuration is working.
thank you once again again

It is true that transient may exercise time behavior of the circuit but this is in case if you change you VIC too fast. If the change is slow enough, then it is pretty much like DC.
Dear Suta,
That is the reason why I would like to run it by transient
