    hi,
    I am doing the simulation of 6T sram cell. I need to measure the static noise margin of the cell using LTSpice. I did with dc sweep analysis and i got some results. But i think it is not the proper butterfly curves to measure SNM. I have read somewhere that we have to swap the graph of second inverter to get the butterfly curve. is it possible to do in LTspice

    can anyone please help me to solve this.
    i have attached the results which i got.
