Debouncer
Maturity simulatedTargets FPGA + ASICDifficulty EasyPriority 1
Debounces N asynchronous switch / button inputs; each input is synchronized and must differ from the debounced state for CYCLES consecutive enabled clocks before the state changes, with rise / fall pulses and a clock-enable for slow sampling.
Simulated. The RTL is lint clean and passes its self-checking testbench against a reference model in simulation. It has not been run on an FPGA board or in silicon.
