BLVDS_25 Slew rate

Hell guys,

 

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.

 

 

Thanks,

 

Kim

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?

 

Thanks,

 

Kim

Hi Kimwen,

 

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.

 

Regards,

Krishna
