2.2.1. Hard IP Rules
When planning for channel placement, follow the location requirements in the table below based on the required hard IP configuration in your design.
Hard IP Configuration | Channel Placement Requirement |
---|---|
Hardened PCIe IP | Fixed locations as shown in Channel Placement for Hardened PCIe IP Configurations Across GTS Transceiver Banks |
Hardened Ethernet IP | CH3 in the GTS transceiver bank as shown in Channel Placement for Hardened Ethernet IP Configuration in the GTS Transceiver Bank |
Hardened USB3.1 IP 6 | CH2 or CH1 in GTS transceiver banks directly adjacent to the HPS block as shown in Channel Placement for Hardened USB3.1 IP Configuration in One GTS Transceiver Bank Directly Adjacent to the HPS Block. Refer to the Agilex™ 3 Hard Processor System Technical Reference Manual for implementation details of USB3.1. |
PCS Direct | Any channel in a GTS transceiver bank, except for lane aggregation requiring bonding where location is as shown in Channel Placement for PMA Direct Configuration for Bonded Lane Aggregation |
PMA Direct |
The figures below show the fixed location placement requirement for various configurations of supported hardened protocol IPs. The PMA channel that supports a particular configuration is shown in the same row as the hardened IP location or configuration.
