What is the use of acclerator mode and normal mode of simulation ?

There are few simulation modes :

Noraml Acclerator Rapid Acclerator PIL SIL External

What are the difference between these modes used for simulation ?

I have generally used Normal mode , Why and When are the other modes of simulation used ?

dosen't the solvers serve the purpose of simulation mode change ?

Please read the Choose a Solver to understand how solvers affect simulation. The comparison between Normal, Accelerator and Rapid Accelerator modes is on this page. There is information about External Mode here, about SIL/PIL here.

Great Thanks for the links :)

just that the external mode and SIL/PIL links requires Licence to access .( which i dont have)

But the links were useful thanks
