I am new to Kicad, I would like to know how to simulate in KiCad

[Nouhou_Issoufou]

Cause I have some trouble simulating transistors and diodes

1. Have you looked at this document for ngspice (instead of KiCAD document)?
   Tutorial: ngspice simulation in KiCad/Eeschema

2. Are you looking for something about BC547?
   Have you set up a model for simulation as described in 1.?

   KiCad ngspice does not provide these special device models with their distribution, you have to look for it elsewhere, e.g. at our Models for ngspice page,

3. models_ugr\modelos_subckt\spice_complete\BJTN.LIB In this file

   .MODEL BC547 ….

and diodes

and diodes???

Simulation: Getting started with ngSpice and other resources

There are quite a lot sources and resources for getting started with ngSpice in KiCad, so I thought to make a list with links instead of repeating the information again and again and again and… Text Tutorials First, of course the ngSpice website itself. The link below is to how to use ngSpice with KiCad, but there is lots of other info over there, from the official ngSpice manual (ngSpice is a separate project then KiCad), to (links to) downloadable libraries with models. Videos If you prefer…

It is not in this circuit but I have the same issue with diodes

What only you can see, only you can solve. I think you’d be happier if you told other people what you’re seeing, but what do you want to know?

Thank you very much tama !!.

In the FAQ article linked to by amit, I collected some resources that help with getting started with simulations in KiCad. I suggest that you start with some simple things, such as downloading a few of the examples and verify they work. Then you can start modifying them, and do things such as substituting your own diodes and BJT’s.
