F. Current Dependent Current Source
Based on what you further clarified in the comments about what you are trying to do, there are a couple things wrong here.  First, you're using a bunch of H-sources (current dependent voltage sources), when it looks like you want V-sources (independent voltage sources).  These are simply called &quot;voltage&quot; in the main component library.  Your 4 rail voltages should be fine setting these to a DC voltage level via a simple right-click on the symbol after you place it.


Second, you're trying to do an AC small signal analysis (.ac) when what you really want is a transient analysis (.tran).  You also need to make this input voltage source a SINE or PULSE waveform.  This is found by right-clicking on the symbol and clicking &quot;Advanced&quot; to bring up the function select menu.


I believe I correctly acquired the model you are trying to use from here:

I auto-generated a symbol similar to yours and here is a screenshot of the correct version of what I think you want to accomplish with your simulation:
