What are the potential pitfalls of a circuit simulator? They are, after, all a computer program that is designed to replicate the actions and events of a circuit through a series of mathematical equations, but being a piece of software means that things can and do go wrong. The hope is that by knowing about them in advance it does make easier to then rectify the problems as you will already know what to do in that situation.
The problem here is that a circuit simulator is just a piece of software, and there is no doubt that it will not be perfect all of the time. Computer software does go wrong from time to time, so even though it will show if your circuit does actually work or not, it is still advisable to check everything more than once before progressing to the actual manufacturing stage.
If you discover that the software is constantly developing errors, then it may be worthwhile downloading it again or checking for any updates on your version as there may be an issue in the coding that is causing the issue.
Next, the major problem is perhaps the fact that a circuit simulator cannot replace what goes on in a lab and by relying on it at every given opportunity it does mean that some skills and hands-on experience is going to be lost.
This in itself is a problem, so the student or electronics designer still has to fully understand how to build test circuits by hand or they will run into problems with the designing of it via the simulator and be unable to react the same to any problems that it shows up.
There are also times where the circuit simulator is just unable to resolve an issue, but this is often down to something that you have entered into the circuit itself rather than a fault with the software itself.
At this point it is always best to strip the potential circuit back to the bare bones and test at every single stage in order to identify the area where the problem lies. This will allow you to rectify the problem and allow the simulator to work correctly once again.
Finally, there is no need to worry about having to continually update the software because even though the latest versions do come with more diagnostic tools than ever before, they do all still offer you the chance to check a circuit no matter how complex or basic it may be. Indeed there are still people out there who are using some of the very first simulators to have ever came out and capable of still getting results.
Those are some of the things that can go wrong with a circuit simulator and at least now you can study how to rectify the problems in advance. This software plays an essential role in advances in the electronics industry and they will continue to be used for some timely come, so deal with the problems and focus on taking advantage of what they can do.
