I am very new to Zybo z7 board. I am trying to program PL (XC7Z010-1) Pmod JC I/O input and output to both 1.8V instead of 3.3V. According Xilinx Zynq-7000 datasheet, PL's Programmable I/O Blocks can be programmed ranging from 1.2V to 3.3V. In Vivado, I can select IO/std to LVCMOS18(Or whatever other than 3.3V), however the output from I/O are always measured at 3.3V regardless what options I have selected under I/O Std. What I am missing here?
