ok, so we have our first lab to do by next weds.. no one understands it.. on top of this we have a quiz on it this coming monday... so can anyone help me understand the question... once i understand that i'll know how to start coding it... here it goes:
"You will design a logic circuit that adds two 4-bit BCD numbers and produces a 4-bit result (Sum) along w/ a Carry bit. ... Write the behavioral and structural VHDL code for a 4-bit BCD Full Adder (using the Carry as an input depends on the model of the adder circuit you are implementing)."
so, thats the jist of it... im sure it's not hard to code... and thats not what im concerned with... i basically just dont understand what we're really doing when it comes down to the circuit/gate level... help please. thanks.
