About pad scheme of i3c prototype on fpga

Hi all, I want to build one i3c prototype on fpga, but I find that all pins can only used as one of the push-pull or open-drain, I don't find that one pin can switch drive mode between push-pull...

Hi ak6dn
So maybe I can use this method currently, and will such pins appear in new FPGA models in the future?

Since I don't work for Intel/Altera, I can't make any comment on this other than 'not likely', in my opinion.

The usage scenario is quite small for this feature, and using two pins vs one is not a big deal in that case.

It is not like you are going to build a controller that needs hundreds of 'I3C' interfaces.
