When we write down a VHDL code, When we write down a VHDL code, we must ensure a good matching we must ensure a good matching between the digital circuit and our between the digital circuit and our modelmodel

Thus, we need to check every Thus, we need to check every signal and monitor the source signal and monitor the source code step by stepcode step by step

With a simulator tool we can easily With a simulator tool we can easily reach these goalsreach these goals
