Modular ADC core Intel FPGA IP ANAIN1 only (pins Channel 1, 2...TSD using as GPIO)

Dear,

I want use Modular ADC core Intel FPGA IP. But ANAIN iput only (10M08SAE144I7G). Another ADC pins (Channel 1, 2...TSD) not, this pins are used as GPIO.

Error (176310): Can't place multiple pins assigned to pin location Pin_6 (IOPAD_X10_Y22_N14)
	Info (176311): Pin PIN_SDRAM_DQ[12] is assigned to pin location Pin_6 (IOPAD_X10_Y22_N14)

Error (176310): Can't place multiple pins assigned to pin location Pin_14 (IOPAD_X10_Y19_N21)

Can I using "Modular ADC core Intel FPGA IP", but ADC bank 1A not? Only dedicated ANAIN pin? I use all other pins to GPIO - not have free pins... :-(

Thank you, Tomas Kapinus
