3.1 SmartDebug Architecture
(Ask a Question)PolarFire devices contain additional logic to support design debug. SmartDebug circuitry
supports the following debug capabilities:
- Live Probe
- Active Probe
- Fabric RAM Block access
- sNVM read access
- Transceiver and DDR debug
- Fabric Hardware Breakpoint (FHB)
The SmartDebug circuitry is mastered by the embedded System Controller, which is controlled by commands over the JTAG interface. The System Controller converts the JTAG commands to various bus accesses to control the SmartDebug logic.
