3.10. The Power Monitor

The Power Monitor measures and reports current power information and communicates with the MAX II device on the board through the JTAG bus. A power monitor circuit attached to the MAX II device allows you to measure the power that the FPGA is consuming.
To start the application, click the Power Monitor icon in the Board Test System application. You can also run the Power Monitor as a stand-alone application. The PowerMonitor(32-bit.exe) and PowerMonitor(64-bit.exe) reside in the <install dir>\kits\<device name>\examples\board_test_system directory.
Note: You cannot run the stand-alone power application and the BTS application at the same time.
Figure 15. The Power Monitor

This window displays both LTC2990 current and temperature monitors. The left side top and bottom quadrant shows U29 and the opposite side shows U30. Use the available controls to show Current or Voltage Single-Ended, or both.

Single Chart Mode allows you to choose how you want the panes to display. You can show only a single large pane, if needed.

Voltage Single-Ended shows the voltage value of each power rail:
  • 2.5 V CORE
  • 2.5 V VCCIO
  • 1.5 V VCCIO
  • 1.2 VVCC
Single-ended shows the voltage of SENSE_P only.

The LT2990 also shows a differential voltage value of the sampling resistor SENSE_P and SENSE_N.

Sample Speed allows you to select Slow at 5 seconds, or Fast: at 1 second (default).

Record Log saves a comma-separated values (CSV) format file ltc2990.csv in the *\examples\board_test_system directory.
