Many times I see buffer ICs used on the IOs of an FPGA.
Most commonly, they are used on those pins that lead to an external connector from the PCB.
As far as I understand, this is done to protect the FPGA... I.E - if something burns out it'll be the buffer IC (that's easier and chipper to replace) and not the FPGA.
What do you think about this design practice ?
Is it really worthwhile ?
