Using manual series and parallel termination for DQ signals Cyclone V

Hi! I get this errors when I try to compile a project with using ALTDQ_DQS2 v17.0 + ALTDLL + ALTOCT in Quartus 17:

I'm working with special FPGA DQ group. RZQ pin is connected to ALTOCT and RZQ is a special pin.

I tried standards: 1.8V (Hyper RAM voltage), 1.8 SSTL class 1, 1.5V (DDR3), 1.5V SSTL class 1.

I tried select different resistor value.

Is it possible to connect to external Hyper RAM memory manualy with ALTDQ IP?

Hi ABely5,

 

Thank you for joining this Intel Community.

 

Based on the error message shown above, seems like the termination value is not comply with the I/O standard used.

 

You can find the supported OCT value and RZQ value based on the I/O standard applied from Cyclone V device handbook in I/O chapter "On-Chip I/O Termination in Cyclone V Devices" (page 143).

Hope this helps.

 

Thanks
