Why does the Intel® Stratix® 10 E-Tile Native PHY IP PMA adaptation parameters fail to load to all channels of a given instance?

To work around this problem in the Intel® Quartus® Prime Pro software version 18.1 Update 1, follow the steps below:

1. Obtain the physical address of Channel 0 (base address of 0x0):

0x200[7:0]: 8’h00

0x201[7:0]: 8’h00

0x202[7:0]: 8’h00

0x203[7:0]: 8’h97

2. Copy to other channels (base address of 0x80000 for Channel 1, 0x100000 for Channel 2, etc):

0x200[7:0]: 8’hADDR

0x201[7:0]: 8’h00

0x202[7:0]: 8’h00

0x203[7:0]: 8’h95

Where ADDR is the physical address of Channel 0 returned in 0x204 from the first set of register writes. 

Please refer to the Intel® Stratix® 10 E-Tile Transceiver PHY User Guide, "Configuring a PMA Parameter Using Native PHY IP" chapter for more information regarding PMA Adaptation Parameters within the Native PHY IP Core GUI.”

This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Edition software.
