10M50DAF672I7G supports 1.0V IO Voltage or not

We are planning to use "10M50DAF672I7G" device on of the prototyping platform. We are looking for 1.0V IO voltage support.

Based on

https://www.intel.com/content/www/us/en/docs/programmable/683751/22-1/i-o-standards-support.html#sam1394013000492__fn_OnlyAvailableForFollowingOPNs

device Supports 1.0V.

But when we tried to synthesize, Quartus tool throwed error

 

r saying that 1.0V IO is not supported.

    Tried with Quartus Prime Version 22.1 Std.

    Error gone away but seeing a critical warning.

    we are planning to use 4 Bank's of the FPGA, IO's expected to toggle at @100Mhz.

    Any suggestions regarding this warning message.

      Hi,
      mutual inductance spec for 1.0 V IO standard is explained in MAX10 General Purpose I/O User Guide. General suggestion to reduce total mutual inductance: leave unused pins in 1.0V bank.
