The fixed time step that could help some time (but should only be a spice option)
The C blocks,
The simplicity to create a PWM controller model Review collected by and hosted on G2.com.
The graphical interface, reloading at each movement,
the "green" and "red" world that lead to confusions (not solved simultaneously)
The solver that you do not know how it works, no information of max iteration at each step or misconvergence issues
The "no convergence problems" of PSIM belief
the no units in m (milli), n(nano), others and even between volts and amperes (in the viewer)
the not well working functionnality of recording every nodes voltages and branch currents to debug a simulation
the no possibility to name the nets that could be enough for the voltmeters not to name them as well
the no possibility of having the result file in a different folder than the model file
the no possibility to view a model file when loosing a remote licence
and they have a nice SPICE option for LTSpice link that you can pay for... Review collected by and hosted on G2.com.
