Hello everyone, hope you're all fine. I have a homework but I can't solve it.
Question is; design a circuit that converts 3 digit bcd number to binary using 74184.
I am using Proteus 8. The problem is that using the IC. When I run the circuit, it gives error " No model specified for U1. [U1] ". I learned to solve this. I pick the Attach Hierarchy Module but this time IC is not working. I mean in the probe side, I see gray squares that refers neither 1 nor 0. How can I solve this ?
Regards,
Thanks in advance.
