Finite State Machine (FSM) merupakan salah satu metode penting dalam perancangan sistem digital yang banyak diterapkan pada perangkat otomatisasi. Penelitian ini membahas desain sistem vending machine berbasis FSM menggunakan Verilog HDL dengan melakukan perbandingan antara metode Moore Machine dan Mealy Machine. Sistem dirancang dan disimulasikan untuk menguji respons terhadap masukan berupa nominal uang dan pemilihan produk. Proses pengujian dilakukan melalui simulasi pada lingkungan Verilog HDL untuk menganalisis karakteristik masing-masing model FSM dalam menghasilkan output sistem. Hasil penelitian menunjukkan bahwa Moore Machine memiliki keunggulan pada kestabilan output karena keluaran hanya dipengaruhi oleh state saat ini, sedangkan Mealy Machine lebih efisien dalam penggunaan jumlah state dan memberikan respons output yang lebih cepat karena dipengaruhi oleh state dan input secara langsung. Berdasarkan hasil analisis, kedua metode memiliki karakteristik yang berbeda sehingga pemilihan model FSM dapat disesuaikan dengan kebutuhan desain sistem digital yang dikembangkan.
