MAX10: Altera GPIO Lite

Hi,  

 

I am trying to use DDR input registers from Altera GPIO lite with "implement ddio input registers in hard implementation" option turned on but fitter fails when this option is turned on.  

I am using max10m16sau169c8 device and as I understand this option should be supported for my device.  

 

In document "max 10 general purpose i/o userguide", table "table 25. altera gpio lite parameters - registers": 

https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/hb/max-10/ug_m10_gpio.pdf 

it says that: 

this option is applicable only for max 10 16,25, 40, and 50 devices because the ddioinput registers hard block is available only inthese devices. to avoid fitter error, turn thisoption off for other max 10 devices.

Can someone help me with this problem?
