5. Block Description

The following block diagram shows the interconnections of F-tile Ethernet Multirate IP instances that are used as power up instance, and profile instances:
Figure 15. Block Diagram

The F-tile is connected to the FPGA fabric using Intel's embedded multi-die interconnect bridge (EMIB) technology. The EMIB Deskew block corrects for possible skew over the EMIB interfaces between the main FPGA die and the F-Tile. Typically, the 40GE/50GE/100GE/200GE/400GE ports access the EMIB Deskew block. The 10GE/25GE ports that use PTP can also access this block.

The TX/RX Data Path (DP) mapping functions map the Ethernet IP signals to the EMIB datapath.

The PTP soft component logic block enables the PTP interface. The block performs the soft logic operations required for the F-Tile timestamp system for 1588 PTP support and connects to the time-of-day (TOD) module.

The PCS interface and the PCS66 interface follows the path through the EMIB Deskew and DP Mapping stages. The interface does not use adapters.

The Auto-negotiation and Link Training (AN/LT) port connects to a separate F-Tile Auto-Negotiation and Link Training for Ethernet Intel® FPGA IP. When enabled, the IP provides the status and control information.

The Reconfiguration and reset logic implement the reconfiguration interfaces and resets for the core, respectively.

Avalon® memory-mapped interface (Avalon MM) Adapters communicate with the F-tile raw Avalon® memory-mapped interface, allowing an 8-to-32 bit conversion on the transactions.

Optional Debug Master Endpoints instantiate the Avalon MM interfaces via GUI options to enable Transceiver Toolkit and Ethernet Toolkit software utilities. This feature is planned for future release.
