tsmc65nm DFM_options

Can someone please tell me, what is the difference between these design for manufacturing options? A brief about these options and how it affects my design?

    You should either read the PDK documentation or contact TSMC about this. I don't think anyone can read answer this (other than in very general terms) without violating NDAs. Very simply though, minRule is just using the minimum design rules, DFM is using larger rules which are better for design for manufacturing (so will improve yield). I assume that DFM+Analog is an extension of that for Analog rules and the custom gives additional fields so that you can override some dimensions yourself. Don't quote me on this though - I'm just extrapolating from memory.

    Hi, I'll steal the last line of Andrew's answer "Don't quote me on this though - I'm just extrapolating from memory":

    min-rules are often reserved for standard cells. TSMC might reject your custom design, if you are not using DFM rules.

    Kind regards,
