Simulation error log Proteus

”Fatal simulation error encountered” you might have faced this error while performing simulation in Proteus. I have read many articles on the internet about how to solve this problem but couldn’t find a satisfactory answer. So I have decided to write a detailed article on this error that will help you to remove this error and will save your time.

Proteus Professional 8.13

Proteus Professional 8.13 is the simplest and most advanced software for designing circuits. In which you will have to search for components, place them in the workspace and connect these with wires and your circuit will be ready. you can also design PCB  with Proteus 8.13.

How to Solve “Fatal simulation error encountered”?

There are different methods to solve this issue, if one is not working then the other will work.

1. Add Libraries:

When you run your simulation a popup window will show displaying

fatal simulation error

when you click on yes then it will take you to another window displaying these error

simulation failed due to fatal simulator errors
  • Now what you all have to do is close this window and stop your simulation.
  • If you are using any sensors like a gas sensor, water sensor, and flame sensor upload the .hex file in them and again run the simulation.
  • The Libraries with .hex Files are easily available here. You can download and use them for free.
  • After doing this you will notice that simulation failed due to fatal simulator errors has successfully been removed.

if the above-mentioned method is not working, move to the next method.

2.  Incorrect .hex file

Another reason for getting real-time simulation failed to start error is the hex file you are uploading is not correct. Uploading the correct file will remove this error.

3. Connections Error

The error occurred due to improper connections like +VCC or GND or any other component or senor. Make sure you have made the right connections.

4. Invalid Value of Component

The simulation error can occur when you have assigned the invalid value to the component that is stopping it from working. For example too large a value of resistor or capacitor etc.

After checking all the above-mentioned steps if you are still getting the error try reinstalling the Proteus because sometimes installation errors can cause this problem.

After reading this article “How To How to Solve “Fatal simulation error encountered? ” you will be able to remove this error. We have tried to cover each aspect of the fatal simulation error and will look for more and try to add those in the next update. Does this work for you? Let us know in the comments section below.
