18.1.1 Naming Conventions for Combinational Cells

The names for combinational cells are composed of the following two parts:

A name identifying the logic function (AND2, NOR3, XOR2, BFR, etc.).
A 2- or 3-character code describing the pin inversions such as TFF. Capital T (true) indi-cates not inverted and capital F (false) indicates inverted. When no inputs are inverted, the inversion code is omitted.

Note: Not all combinations of inverted inputs are available. We have limited the number to avoid redundancy (e.g. AND2FF is logical equal to NOR2).

AND2FT - The cell is a 2-input AND gate. The pin inversion code FT indicates that the A input pin is inverted, and the B input pin is not inverted.

AOI21FTF - The cell is a 3-input AND-OR-INVERT gate into a 2-input NOR gate. Pins A and C are inverted, pin B is not.
