of_q_time_tagger
Multi-channel time tagger
Maturity plannedTargets FPGA + ASICDifficulty HardPriority 1
Timestamps detector events on many channels against a common reference and streams time tags with rate filtering and channel delays.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
