This is my test project for which I am trying a transient simulation:
https://easyeda.com/editor#id=|0aba11fae8a34a039ccdb860076db290

I used these settings:   Max Timestep: 10u, Stop time: 4m, StartTime: 0

And got the following errors can anybody help me with finding what causes this please :

Circuit: gooduntitled

Doing analysis at TEMP = 27.000000 and TNOM = 27.000000

Sorry but I don't have access to a PC at present so I can't see your schematic properly.

In the meantime please see:

There are two problems in your simulation schematic.

  1. You have no power supply. See "Avoiding common mistakes" in the Simulation Tutorial:

https://docs.easyeda.com/en/Simulation/Chapter1-Introduction/index.html

  1. You have chosen transistors that are not from the Spice Simulation symbol library. See:

https://docs.easyeda.com/en/Simulation/Chapter1-Introduction/index.html
