Hi all,
Quick question regarding setting the IO standard level in a projects UCF file.
I have a port which interfaces with some 5V logic, on bank 3 of my spartan 3A. So I have connected the VCCO3 to the 5V supply. but now when I'm looking to set IOSTANDARD attribute in my UCF file (and checking the documentation on page 340) it seems that there is no 5V standard available for this FPGA :-?
Is there any standard which will use the 5V attached to VCCO3, allowing proper communication without damaging the FPGA?... or will I have to start cutting some tracks :-x
Cheers,
Mike
