NAND Primitive
| Names: | Output Description: | Input Description: | 
|---|---|---|
| NAND2,NAND3,NAND4,NAND6,NAND8 ,NAND12 | OUT = logical NAND of inputs | IN1, IN2, ...IN12= 2, 3, 4, 6, 8, or 12 inputs | 
Note:  In Verilog HDL, you must use the built-in nand gate primitive to
            implement the NAND logic function. Go to Using a Verilog HDL Gate
            Primitive for more information.
