Why does the Low Latency Ethernet 10G MAC's dynamic generated multi-rate example design fail compilation for Stratix 10 device?

Description

Due to a problem with Intel® Quartus® Prime version 17.1, the Low Latency Ethernet 10G MAC's dynamically generated multi-rate example design will fail compilation if the "Analog Voltage" setting is changed to 1_1V in Low Latency Ethernet 10G MAC example design GUI. 

The following are the affected multi-rate example design variants:

  1. 10G USXGMII Ethernet Example Design (Intel® Stratix® 10)
  2. 10M/100M/1G/2.5G/10G Ethernet Example Design (Stratix 10)
  3. 1G/2.5G Ethernet with 1588 Example Design (Stratix 10)
  4. 1G/2.5G/10G Ethernet with 1588 Example Design (Stratix 10)

Workaround/Fix

To work around this problem, launch the IP Parameter Editor of the following IPs from the generated multi-rate example design project, and manually change the setting for "VCCR_GXB and VCCT_GXB support voltage for the Transceiver" to 1_1V. 

  1. Stratix 10 L-Tile/H-tile Transceiver fPLL (Open the .ip files which located in <project_directory>\rtl\pll_fpll and change the settings)
  2. Stratix 10 L-Tile/H-tile Transceiver ATX PLL (Open the .ip files which located in <project_directory>\rtl\pll_atxpll and change the settings)
  3. 1G/2.5G/5G/10G Multi-rate Ethernet PHY (Open the .ip file which located in <project_directory>\rtl\phy and change the settings) 

 This problem has been fixed in Quartus Prime version 17.1.1.
