It is. If I understand you correctly... instTerms are used to define the
connections to an instance.
You would create instTerms if you had instances in your pcell, which is
not the case.
To create pins, first create a net, then a terminal on that net, and
finally a pin on that terminal/net.
You'll just need a shape/instance to associate with the pin ; it defines
the physical connection
point. In a layout, it can be a piece of metal ; in a schematic an
instance of
basic/(ipin|opin|iopin) ; in a symbol, a simple rectangle....
