2.14 High Speed Serial Interface Configuration Path - IGLOO2 Initialization

You must use System Builder for IGLOO2 designs that use the SerDes block. System Builder generates an APB bus to handle the internals of the High Speed Serial Interface Configuration Path used for the initial SerDes block configuration and initialization.

The SerDes block is always configured as an APB Slave to the System Builder Block; it cannot be configured as a master. You must configure a fabric master to use the SerDes block as a slave.

After generating your System Builder Block, you must connect the SerDes configuration path signals to the System Builder Block:

  • Connect the APB_SLAVE BIF of the SerDes block to the corresponding slave BIF of the System Builder block.
  • Connect the APB_S_PCLK port of the SerDes block to the INIT_APB_S_PCLK port of the System Builder block.
  • Connect the APB_S_PRESET_N port of the SerDes block to the INIT_APB_S_PRESET_N port of the System Builder block.

SerDes initialization data are automatically loaded into the SerDes initialization registers during device bootup.
