Error: hard_etile.alt_ehipc3_0: "Select Ethernet Rate" (ehip_rate_gui_sl_0) "10G" is out of range: "25G"

Description

When using Intel® Quartus Prime Pro software version 18.0, and selecting '1 to 4 10GE/25GE with optional RSFEC' or '100GE or 1 to 4 10GE/25GE with optional RSFEC and 1588 PTP' core variants for the E-tile Hard IP for Ethernet Intel® FPGA IP, the error message above is seen if the ' Select Ethernet Rate' parameter is set to 10G and the 'Enable RSFEC' parameter is also enabled.

 

The E-tile Hard IP for Ethernet Intel® FPGA IP does not support RSFEC for any variant with 10G channels.

Workaround/Fix

For successful IP generation process, users are advised not to select the "Enable RSFEC" option for 10G Ethernet rates, as 10G speed mode is not supported. Please refer to the E-Tile Hard IP for Ethernet Intel® FPGA IP User Guide, figure 1, for supported variants of the IP.

Starting in Quartus® Prime software version 18.1, the E-tile Hard IP for Ethernet Intel® FPGA IP GUI will prevent unsupported parameterization combinations.
