4 Select Enable Soft PCS to achieve maximum data rate. For the TX IP core, enabling soft PCS incurs an additional 3–8% increase in resource utilization. For the RX IP core, enabling soft PCS incurs an additional 10–20% increase in resource utilization.
5 When using Soft PCS mode at 15.0 Gbps, the timing margin is very limited. You are advised to enable high fitter effort, register duplication, and register retiming to improve timing performance.
6 Refer to the Arria® 10 and Stratix® 10 Device Datasheet for the maximum data rate supported across transceiver speed grades and transceiver power supply operating conditions.
7 For Arria® 10 GX 160, SX 160, GX 220 and SX 220 devices, the supported data rate is up to 12.288 Gbps.
8 For Arria® 10 GX 160, SX 160, GX 220 and SX 220 devices, the supported data rate is 11.0 Gbps.
9 For Arria® 10 GX 160, SX 160, GX 220 and SX 220 devices, the supported data rate is 10.0 Gbps.
10 When using Soft PCS mode at 12.5 Gbps, the timing margin is very limited. You are advised to enable high fitter effort, register duplication, and register retiming to improve timing performance.
11 Enabling Soft PCS does not increase the data rate for the device family and speed grade. You are recommended to select the Enable Hard PCS option.
