Power Measurement
There are 11 power supply rails which have on-board voltage and current sense
capabilities. These 8-channel differential 24-bit ADC devices and rails are split from
the primary supply plane by a low-value sense resistor for the ADC to measure
voltage and current. A serial peripheral interface (SPI) bus connects these ADC
devices to the MAX II CPLD EPM2210 System Controller.
Figure 2–11 shows the block diagram for the power measurement circuitry.
Table 2–41 lists the development board power components and its manufacturing
information.
