Hello,
I am using spartan3 FPGA board to detect data as logic 1 for voltage level greater than 3V and logic 0 otherwise.
I am stuck on setting the IO standard for output of FPGA. I did write a ucf file and was just sending random signal varying from 0v to 4v to the Input pin and the Spartan 3 FPGA is detecting any signal greater than 2.3V as logic 1.
Could anyone suggest me how to change the IO standard of Spartan 3 FPGA to 3V.
Any suggestion would be greatly appreciated.
Thanks in advance!!
