2.2. Reference Design Component Blocks

The reference design partitions the functions into multiple component blocks.
Figure 3.  Multi-Rail Power Sequencer and Monitor Design Blocks


You can remove any blocks you do not need and customize the sequencer for the most cost-effective implementation:

  • If you need only a simple sequencer that bases its control on the state of the POK signals, you can use the Power Sequencer component alone.
  • If you want to monitor voltage rails but do not require PMBus* support, you can remove the PMBus* Slave to Avalon®-MM Master Bridge component.
