I have many types of transistors in my PDK
some have in their name mac for example nch_mac and nch_25_mac.
I don't understand what does the mac stand for and what does it add to the transistor!
Thanks in advance

I can't say anything specific about your PDK; I would expect the documentation from the foundry should explain this. In general, the "macro model" subcircuits can add things like well diodes (esp for pmos), or additional equations for layout-dependent effects (lod stress model, well proximity effect), and sometimes can also include additional parasitic elements (contact resistance, or capacitance between the drain and source contacts, etc.).

If at first you do succeed, STOP, raise your standards, and stop wasting your time.
