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.
