Board overview
The 8MPLUSLPD4-PEVK consists of two separate boards: 8MPLUSLPD4-PWR (CPU board that supports power measurement)
and 8MPLUS-BB (Base Board). It is software-compatible with the 8MPLUSLPD4-EVK. The 8MPLUSLPD4-PEVK board can
measure 27 power rails, including 7 power rails that have dual-range options, for low-power measurement. All PHY power rails
are separated for measurement, so you can conveniently obtain the power consumption for each analog PHY.
2.1 Power rails
Table 1 lists the detailed information of the tested rails.
