5.2. System Power-On

The figure shows the state of operation of the SmartVID Controller IP core during system power-on with the relevant Arria 10 sub-systems.
Figure 3. Operation Behavior

When the CC1[0] register is 1, the IP core initiates VID fuse-read. The SmartVID Controller IP core then switches to SmartVID mode when the following conditions are met:

  • SmartVID logic enabled.
  • The external controller reads out the default VID value and asserts vidctl_vid_ack.
  • The duration specified in the CC2[20:1] register elapses.
