9.21.15 Device Status Report: Analog Block

The Analog block of the SmartFusion® and Fusion devices monitors some of the key power supplies needed by the device to function. These power supply status is captured in the OABTR test register in the Analog block.

For example, if you run Device Status when the Fabric and Analog configuration is programmed and powered up successfully the report indicates:

Analog Block:
OABTR Register (HEX): 0dbe3bb
3.3V (vdd33): PASS
1.5V (vdd15): PASS
Bandgap: PASS
-3.3V (vddn33): PASS
ADC Reference: PASS
FPGA_Good: PASS
Status: Analog Block is operational

Table 9-46. Device Status Report - Analog Block Description
Analog Block Status	Description
OABTR Register	RAW data captured from the device
3.3V (vdd33)	Vcc33a supply status
1.5V (vdd15)	Vccnvm supply status
Bandgap	Internal bandgap supply status
-3.3V (vddn33)	ADC reference voltage status
FPGA Good	FPGA array or Fabric status

If the Fusion device is erased, the report indicates:

Analog Block:
OABTR Register (HEX): 188e3ba
3.3V (vdd33): PASS
1.5V (vdd15): PASS
Bandgap: PASS
-3.3V (vddn33): FAIL
ADC Reference: FAIL
FPGA_Good: FAIL
Status: Analog Block is non-operational
Analog Block is not programmed
