Have you ever set BLVDS_25 slew rate attribute "fast" in vivado?
I tried and got warning that slew rate of BLVDS_25 is not supported in Artix.

I used Spartan6 BLVDS_25 IOBUFDS in my last project,
the output slew rate is very fast by default,I don't need to adjust slew rate attribute.
However,the default slew rate of BLVDS_25 in 7 series FPGA is "slow",which doesn't fullfill my design requirement.
Can I have a work around to open "fast" option in any way?

As suggested in UG471, BLVDS_25 doesn't have an option to specify the slew.
You don't have any workaround to convert the slew rate to fast.
