Does anyone have a 8 bit adder simulation in proteus? I need to add upto 1 to 99.

How much money you got?

Well, 8 bit adders are extremely rare, valuable, and very, very fragile.

I'd give you mine, but the shipping is going to be expensive.

 

MOD NOTE: Moved to Homework Help.

You need to show your best attempt to solve your homework assignments. Then we can help you get over your sticking point. It's also helpful for you to tell us exactly what the assignment is, so that we know what direction we should be steering you in.

 

Well the homework is to create a calculator circuit that add's up to 99 I just need a simulation in proteus and solder it in a PCB.

Yeah. Its okay.

 

I tried looking online but I cant understand the circuit or simulation. I used 7483, 7447, 7 segments to display the digit

 

I'm assuming that the intent of the assignment isn't for you to get a design from someone else and show that their design works. The would imagine that the idea is for YOU to design a circuit that implements the desired functionality.

Let's start with how the numbers that are going to be added are supposed to be entered? What have you done in that regard?

No my teacher said to search online so and put it in a PCB so I have to solder it but I cant find any circuit. The instructions is the circuit uses 2 7483, 2 7447, two 7 segment to display the digits and one 7 segment counts one's and the other in ten's. It should add up to 99

I thought about using 74192 IC but it only add up one(1).

 

Well, I clearly don't understand the intent of whatever course you are taking. It makes no sense to me to have students search online to find a circuit that uses specific components, and for a particular simulator, such that, even if they happen to find something, all they are expected to do is put it on a PCB and wire it up. That results in almost zero learning and I'm not interested in supporting that approach instead of expecting them to actually learn something by actually reading the datasheets for those components and actually designing the circuit themselves.

 

The instructions is the circuit uses 2 7483, 2 7447, two 7 segment to display the digits and one 7 segment counts one's and the other in ten's.

Then what he is asking for is a two digit BCD adder, not an 8-bit adder.

 

The use of two seven-segment displays does not necessarily mean that it is adding BCD numbers. The seven segment display can be used to display hex numbers. Two of them would be capable of 00-FF.

 

Having said that the 7447 doesn't really display hex digits a-f, so that isn't helpful. And I don't see where the 7483 has any method of handling a base 10 carry which also isn't helpful for BCD numbers.

 

that isn't

Thanks for the answer. How about 74192?
