Typical Simulation Parameters

As PSpice was originally not designed for power electronics and highly non-linear
components, the standard simulation parameters (Simulation Setup/Options) are often not
suitable. In common, the following typical values facilitate convergence:

ABSTOL= 1nA (maximum current accuracy)
CHGTOL= 1pC (maximum charge accuracy)
ITL1= 150 (maximum number of iterations for DC analyses without initial conditions)
ITL2= 150 (maximum number of iterations for DC analyses with initial conditions)
ITL4= 500 (maximum number of iterations for transient analyses time
