of_sc_retention
State-retention flip-flops
Maturity plannedTargets ASIC (CMOS) onlyDifficulty HardPriority 2
Balloon and live-slave retention flops with save/restore or single-control retention, powered from an always-on supply in switched domains.
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.
