Hi, I am a new user of FPGAs and I have the CmodS6 kit and I am having in the IO 1.8 V and I need to change it to 3.3V , my ucf shows: NET "PORTA<0>" LOC = "P5" | IOSTANDARD = LVCMOS33 | PULLUP; Vcc is 5V from my usb port and I see at ucf CONFIG VCCAUX = "3.3"; I also had a look at ug381 cdg and ug382. Thanks for your help.
