SDNF and SKNF are two classic methods for synthesizing digital circuits using a truth table. Both are universal, but modern practice uses more efficient methods such as Karnaugh maps and automatic minimization algorithms.
SDNF is the logical OR of all sets of variables where the function is equal to one. SKNF is the logical AND of all sets where the function is equal to zero. The choice between them depends on which rows are more numerous in the table. A logic gate circuit is assembled from the resulting expression: SDNF produces an AND-OR structure, while SKNF produces an OR-AND structure. Before assembly, the expression is necessarily simplified to simplify the circuit. In practice, minimization is performed after synthesis to reduce the number of gates and reduce cost.
