    Hi guys

    Is that a (easy) way to find the area of a waveform in LTSpice, like this one: (I need to estimate the average power dissipation of the mosfet.

    Easy.
    Run sim.
    Cursor on FET.
    Left-click while pressing and holding Alt.
    You will get a plot of the FET dissipation.
    Hold Ctrl, left-click on plot title.
    You get a pop-up box showing Average and Integral.
