if we mentioned IOSTANDARD in the xdc , Exactly what tool will do with this ?

Jump to solution

Hi Friends, 

if we mentioned IOSTANDARD in the xdc , Exactly what tool will do with this ?

1) When Loading bitstream will that do any IO configuration ?

2) what is the purpose of mentioning this ? For Internal design analysis while implementing ? 

Any suggestions or help is highly appreciated. 

Thank You 

S Sampath

Hi @ssampath.

The PMBus usage would be a question might be better suited for the 7 Series FPGA or Configuration boards. For Implementation flow purposes, it is required to be set by the user to a non-default value.

Hi @ssampath.

The IOSTANDARD would set the ports physical signaling standard such as LVDS or LVCMOS18. The SelectIO Guide has more information on each standard available. The property/constraint is then applied to the package pin.

HI @marcb,

 

Thank You,

My doubt is, using PMBUS we will configure all BANKS IO voltages. what is the use of mentioning IO standard in the vivado ?

For example: 

I have configured all BANKS in the FPGA to LVCMOS18 using PMBUS. if i implement design with IOSTANDARD LVCOMS25 then what will happen ?

I Hope you understand my question.
