9 Appendix: Power Monitoring
The SmartFusion A2F200 device on the PolarFire Splash Board has an in-built power monitoring
program that monitors the voltage and current on different PolarFire power rails, as well as the total
device power, eliminating the need for any manual measurements. The power measurements for various
components are displayed in the Microchip PowerMonitor GUI installed on the host PC.
The power monitoring program does the following:
• Monitors voltage on all PolarFire power rails.
• Measures current and power on the following rails:
• VDD_REG: Power supply for fabric core.
• VDDA_REG: Power supply for transceiver and common circuits.
• VDDA25: Power supply for transceiver PLLs. This supply is isolated from other power supplies
to keep the noise low and avoid leakage for PCIe, EXT_PLL, and GPSS.
• VDD25_DUT: Power supply for the eight corner PLLs on the PolarFire device and the sNVM.
These are tied together at the package level to keep the noise on the standalone PLLs low.
• Powers up and powers down the board when pins 2 and 3 of the J4 jumper are closed.
• Powers down the board if voltage threshold violations are observed on a power rail.
The analog computing engine block in the SmartFusion device is configured to measure the voltage and
current on the PolarFire power rails. The following illustration shows the PolarFire power monitoring
process block diagram.

9.1 Prerequisites for Installing PowerMonitor
Before installing PowerMonitor on the host PC:
1. Download the PowerMonitor application from the following location:
http://soc.microchip.com/download/rsc/?f=Polarfire_Splash_Kit_Power_Monitor
2. Ensure that pin 1 and 2 of the J4 jumper are closed.
3. Connect the mini-USB cable from J1 to the host PC.
4. Connect the power supply to J2, and turn ON the SW1 switch.
5. Ensure that the screen resolution of the host PC is at least 1280 × 720. The screen resolution can be
set from Control Panel > Appearance and Personalization > Display > Adjust screen resolution.
6. Ensure that the text size in the display settings of the host PC is set to either small (100%) or
medium (150%). The text size can be set from Control Panel > Appearance and Personalization >
Display > Make text and other items larger or smaller.
