Power Module Grouping

This design example uses three power modules. Each power module powers different power rails for the Intel® Arria® 10 device.

Table 1.  Power Module Grouping
Group Nominal Value (V) Power Rails on Intel® Arria® 10 Device
1 0.9 VCC, VCCP, VCCR_GXB, VCCERAM
2 1.8 VCCPT, VCCH_GXB, VCCA_PLL
3 1.8 VCCPGM, VCCIO

Each power group has different threshold and ramp voltage limits. The preset values are defined in the program in main.h. You can update the threshold and ramp voltage via UART using the THRESHOLD or RAMP command.
