hello everyone,
i'm trying to simulate flip-flop circuits using nand gates only (cross-coupled nand gates) for a school project with PSPICE. however the outputs of my nand gates ( Q and Qnot ) always seem to be at the "don't care" (or "X") state after i run the simulation. is this because the simulator doesn't know what are the initial states of Q and Qnot. is there a way around this? any help is appreciated. thank you.
