We consider simulating finite automata (both deterministic and nondeterministic) with context-free grammars in Chomsky normal form (CNF). We show that any unary DFA with n states can be simulated by a CNF grammar with O(n 1/3 ) variables, and this bound is tight. We show that any unary NFA with n st
