    Hai Everybody,

    This is anil. I am new to this forum. And i have a problem in simualating the RS Flip-flop. I am unable to get the output for the circuit. The netlist which i have given below.

    *netlist for the circuit
    .control

    run

    .tran .01n 4n

    vR vR 0 DC 0 pulse(0 1 2n 0 0 2n 4n)

    can anybody what is the problem in the netlist. If it is wrong, can anybody correct and send to me.

    Thats help me alot.

    Hope anybody can help

    Thank you

    Can you post your listing file? Is there any error reported there? If not what do the waveforms look like? Sketch and post if possible.

    Which SPICE simulator are you using?
