How do I build and simulate a T Flip-Flop without a reset in SystemVerilog?
As for &quot;how is this handled in gate level simulation&quot;, I've done vlsi design in industry for 15 years and I've never seen a T flip flop since college. A TFF without reset is nonsensical since you can never know what the value is. You could conceivably make a circuit that asserts T if the output is 1 through some FSM that activates once, to put the TFF in a known state. I would call that &quot;reset&quot;.
But if you insist, some simulators have a mode to randomly initialize every flip flop in the design. This can be helpful for gate level sims.
