Is it possible to force psim to use more cores? From the task manager looks like it does not use massively the cores. just 20% of CPU usage (spread across the cores? maybe). My CPU is an 11th gen Core™ i5-1135G7 @2.40GHz

    For a single simulation PSIM can not.
    Simulation is a sequential process. It has to be done one time step and use the result for next time step.
    It is also not easy to divide the circuit to pieces. Everything is usually inter-dependent, and we have to follow the sequence.

    The multiple CPU can be used if you run parameter sweep. Each simulation will run on a different CPU.
