Synchronous stack (LIFO)
Maturity simulatedTargets FPGA + ASICDifficulty EasyPriority 1
Single-clock last-in first-out stack of any depth with top-of-stack output, simultaneous push/pop (replace top), occupancy count, overflow / underflow pulses and synchronous clear.
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.
