Codiode/Problems/Sequential Logic

Clock Phase Shifter 180 Degrees

EasyLogic CircuitTiming Diagram

A logical inverter immediately negates its input, while a negative-edge-triggered D flip-flop captures its input only on the HIGH-to-LOW transition of the clock.

Four signals are shown: CLK (clock, period 2), D (data input), CLK_INV (combinational output), and Q_NEG (sequential output, initially 0).

Trace CLK_INV and Q_NEG across all 10 time steps.

Constraints

  • CLK_INV must be evaluated combinationally at every time step based directly on CLK.
  • Q_NEG only updates its internal state when CLK transitions from 1 to 0.

Solve this problem

Place the gates, wire them up and watch the signals settle. Every submission runs on the same simulation engine that grades it.
