Simulation Time Step (Hmin, Hmax)
– Hmin (Minimum time step)
is set so the simulation can
capture fast transients
– Hmax (Maximum time step)
is set so the simulation can take
the largest steps possible during
times where the waveforms are
not changing much. This helps to
speed up Simulation
– Note also the Hmax can be set to
force steps that yield higher
fidelity waveforms
– Note also can set Hmin = Hmax
for fixed time step operation
