Lo scopo di questo lavoro di tesi è quello di riprogettare ed analizzare i requisiti, con uno studio dettagliato, di una interfaccia analogico/digitale per le macchine di comunicazione prodotte da SITTI s.p.a, chiamate MULTIFONO®. Questa ricerca si concentra principalmente su uno dei prodotti MULTIFONO® M600S: Junction Box (JB). Il risultato di questo lavoro è, a seguito di obsolescenze di componenti elettronici, sostituirli con componenti sul mercato garantendo le stesse funzionalità di prodotto. Comprende la selezione e l'integrazione di componenti elettronici in una soluzione economicamente vantaggiosa, sviluppo di PCB, software per una CPLD, generazione di Bill of Material (BOM) e test su prototipo. Le interfacce del sistema identificate, sono state valutate e selezionate in base alle limitazioni dell'hardware. Al termine, vengono proposte alcune modifiche alla struttura meccanica esistente per garantire maggiore robustezza. Questa ricerca include uno studio approfondito sugli aspetti strutturali, funzionali, tecnici e logici di M600S Junction BOX. I diagrammi logici, la modellazione circuitale, la selezione dei componenti e la programmazione CPLD sono stati punti focali nello sviluppo di questa tesi per implementare il nuovo design. Dopo lo sviluppo del PCB, sono state scritte delle procedure di test e dei codici di test in VHDL per verificare il prodotto ed il routing sul PCB. Il software di test e la parte hardware sviluppata sono stati inclusi in un banco di prova. I risultati ottenuti hanno soddisfatto le attese e si sono rivelati migliori rispetto alle attese. E’ stato implementato un prototipo funzionale e le funzionalità di base sono state dimostrate con successo.
