Debugging Circuits

 

I. Objective :

To learn techniques for debugging circuits in a systematic manner.

 

When a complicated circuit is first built, is not uncommon for the circuit to be non-functional, due to wiring/connection errors, faulty parts, and/or incorrect equipment settings (e.g. wrong power-supply settings). The process of finding and correcting these problems is called debugging.

 

II. Debugging Steps:

1. Check the actual wiring against the schematic. One method is to simply verify what is connected

to each node.

2. Check the plug-pin circuit boards. They are notorious for bad connections.

3. Check the power bussing: Are all of the DC voltages correctly distributed?

4. If all of the fixed DC values are correct, check the operation of the actual components. (For

example, measure the DC and AC voltage values at the input and output nodes of an op-amp to

determine if it is working properly.)

5. If a component is suspected to be faulty, first verify that it is really hooked up correctly, then

check to see if it is functional.

6. If the circuit can be divided into stages or modules, check each one of them separately. Verify that

each stage or module of the circuit is functional. (Isolate the bug and eliminate it!)

 

III. Rules:

• Circuit debugging is done with team work

• Each team can have a maximum of 2 members

• There will be 3 rounds

 

ROUND 1:

• Simple questions round 25 questions will be given

• 20 minutes time will be given

 

ROUND 2:

• 5 Simple circuits layout  printed on paper along with their names and components  will be given to each team

• In accordance to the names suggested , the circuits are to be corrected

• Only 30 minutes time will be given.

 

ROUND 3:

• The final round is a hardware round

• Bugged circuits will be given to you

• Circuits must be corrected and the required out graph must be shown to us on the CRO

• 2 circuits will be given and the time lap is 30 minutes.
