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.

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
