I tried building a small project in ISE 10.1 using the CoolRunner II CPLD XC2C128 and ran into a problem with pullups. I defined a few inputs with pullup in the UCF file, and the mapper complained about a conflict between keeper and pullup on the same pin. I had to set unused pins and inputs to default to pullup to get rid of the error, otherwise I just got the keeper and no pullup. it seems the ucf command for pullup isn't being obeyed. Is the CoolRunner II only able to have pullups if they are used on all (input) pins?
Thanks,
Jon
