Inspect the PCB and solder joints
If you designed a PCB for your project, make sure to inspect the pads, traces, and solder joints on the board. Thin traces can be quickly destroyed, and it’s also fairly easy to lift a pad, especially when you aren’t practiced in soldering. Therefore, always verify that there aren’t any broken traces or lifted pads.
Furthermore, you should inspect the solder connections on the board. Make sure that all pins are connected, and there aren’t any bridges present where they should not be. You can use the continuity function of a multimeter to test for broken traces and shorts. Lifted pads and solder bridges can be found by visually inspecting the PCB.
Check the Specs
Our AUS Assignment Help states that like any other circuit, it’s important to take a look at the specifications of the components in your design. Double-check the datasheets of the parts because they contain valuable information, including timing descriptions, pin diagrams, maximum ratings, and much more.
Inspect the Outputs and Inputs
Next, look at what the components do in your design, and check whether it differs from what you expect them to do.
You can use various tools to inspect the I/O pins of digital ICs. The simplest tool is an LED. An LED allows you to quickly determine whether a pin is HIGH or LOW. The same can be accomplished with a multimeter or a simple logic probe.
However, those are only viable options when you want to troubleshoot a slow synchronous or asynchronous digital circuit. For any other type, I recommend using an oscilloscope to look at the signals over time.
Make sure to inspect every signal of the circuit. I prefer to start at the output of the circuit itself. If it's correct, then you’re done. Otherwise, you have to take a look at the input pins of the device that produces the output.
The Digital Circuit Assignment Help advises you to check whether the input signals are what you expect them to be. If they are, then the device itself might be broken If the inputs are incorrect, look at the next device in the chain (the one that produced the incorrect signal). Repeat these steps until you find the point of failure.
