Ferramentas de suporte ao estudo da Disciplina de Sistemas Digitais: Mapas de Karnaugh

This article intends to reveal a tool for Boolean functions simplification, developed in the scope of the Digital Systems program, part of the Mathematical Education Project. The document begins by showing some work examples, describes the technology used in the project, it enunciates and describes (with examples) all the steps of the algorithm and finishes by illustrating graphically the results gathered in laboratory. We highlight the relevant way how it was implemented, having as immediate goals the utility of the tool, the ease of usability, in a well disseminated platform (MS Excel), although specially created for Windows. Beyond all these interests, it still refers the capacity of the algorithm bares some fragilities of tools as the Espresso that, although having better performance, it shows, in rare cases, signs of smaller efficiency.
