Supply droop detector
Maturity plannedTargets ASIC (CMOS) onlyDifficulty HardPriority 1
Fast on-die voltage droop detector using tunable delay lines or comparators, raising an early warning for clock stretching.
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.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| vdd_sense | inout | analog | 1 | |
| droop | out | serial | 1 | |
| level | out | parallel | 6 |
