HMC pins in the CycloneV

Hello. 

I plan to use 5CSEMA5 with hard memory controller and single SOC core. HMC in the FPGA part of 5CSEMA5 has got a lot of pins for DDR3 connection.  

I want to use only part of special HMC pins for connection to DDR3. 

Can I use free pins of HMC (for example DQ[16 - 39]) as IO and use their for other signals?  

 

Thanks.

Hi, 

 

If hard memory PHY is used, You can connect unused pins as defined in the Quartus Prime software. 

Refer below links.
