    For Atmega328p after the proteus simulation runs for a few seconds
    I get the following error

    [SPICE] DELMIN increased to 1.77636e-015 due to lack of time precision
    [SPICE] TRAN: Timestep too small; timestep = 8.29197e-016: trouble with node #MOTOR#0007#00138.

    Check attachment for circuit schematic(Final_With_MAX)

    AND SURPRISINGLY when I add an LED without any connections(Final_With_MAX_extra)
    The simulation runs till the end

    I have tried everything...

    No idea what is wrong
