Active shield mesh
Maturity plannedTargets ASIC (CMOS) onlyDifficulty HardPriority 2
Top-metal mesh driven by pseudo-random patterns and checked at the far end to detect probing, cutting and rerouting.
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 |
| mesh_out | out | parallel | 16 | |
| mesh_in | in | parallel | 16 |
