- Introdução
O projeto de sistemas digitais 3 está sendo uma máquina de bilhetes automatizada, que temos bilhetes de ida , ida e volta e um 1 dia, que foi desenvolvido via rede de petri e as especificações foram divididas para cada grupo com isso temos a construção da ideia do projeto a baixo iremos colocar a rede petri em blocos e o código VHDL .
