2.7.4.1. Channel Placement

Depending on the number of bonded PMA channels, the Channel Placement tool supports two E-tile variants, 24-channel placement and 16-channel placement variant.

In Intel® Stratix® 10 devices, each E-tile provides Hard IP for up to 4 100G Ethernet channels, and up to 24 10G/25G Ethernet channels. In Intel® Agilex™ devices, each E-tile provides Hard IP for up to 4 100G Ethernet channels, and either up to 24 10G/25G Ethernet channels in 24-channel bonding configuration, or up to 16 10G/24G Ethernet channels in 16-channel bonding configuration.

Figure 10. Ethernet Hard IP Overview

The figure shows an example placement of the channels using the E-tile Channel Placement Tool.

RS-FEC is configurable for single-lane 10G/25G and multi-lane 100G Ethernet interfaces.

Figure 11. Ethernet Cores Position on an E-tile Device

You can place the core by constraining a serial pin from the core to one of the transceiver pins on the selected E-tile device. For example, if you constrain the serial pins from a Variant A core to transceiver pin 10, the core will be placed in Variant A position 10.
