Error: tmp.alt_ehipc3_0: "Select Ethernet IP Layers" (ehip_mode_gui_sl_0) "MAC+PCS" is out of range: "MAC+PCS+RSFEC"

Description

When using Intel® Quartus Prime Pro software version 18.0.1, 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 have RSFEC support for any variant with 10G channels.

Workaround/Fix

For successful IP generation process, users are advised not to select the "Enable RSFEC" option in 10G Ethernet rates, as this variant 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.
