VREFB<#>N0 pin connectivity on MAX10

NSV00

I am doing a design with MAX10 FPGA (10M25DAF484I). I am using both the internal ADC IPs and i have connected the ADC_VREF pin to a reference 2.5V power supply.

Right now i have not connected VREFB1N0, VREFB2N0, VREFB3N0, VREFB4N0, ...VREFB8N0. Can i leave all the VREFB<#>N0 pins unconnected? Or what should be the recommended connectivity?

The connection guidelines document says that: "If you are not using the VREF pins in banks or shared banks, connect unused pins as defined in the Intel Quartus Prime software" But i don't have any Quartus software installed to check.

I need to freeze on the hardware quickly. So please reply.

Hi Nagendra SV You can refer to Pin Connection Guidelines: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/dp/max-10/PCG-01018.pdf To set up the unused pins behaviour: In Quartus Prime tools, Go to Assignments -> Device -> Device and Pin Options -> Unused Pins tab and set the behaviour of unused pins. Thanks. Regards Eng Wei

Hi Nagendra SV

 

Do you have any question regarding the unused pins before we proceed to close the ticket?

 

Thanks.
