Hi, Do FPGA IC's pin able to switching between LVDS and LVCMOS in one program? 

If yes, how do I configure it? 

Let said I used one pin to switch IO pins. 

When logic '1', all my IO pins become LVDS pair. 

When logic '0',all my IO pins become LVMOS pin.

Hi, 

 

You cannot change the IO type of Pins on the fly. You will have to assign the pins either to LVDS or LVCMOS in the Assignment editor.
