Coincidence counter
Maturity simulatedTargets FPGA + ASICDifficulty MediumPriority 1
Programmable multi-fold coincidence logic with per-pattern windows and counters for photon correlation experiments.
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.
