William25 Posted March 13, 2016 Report Share Posted March 13, 2016 Hi, I've encountered a problem that I can't program arrays in the UCF.When I try to program an array in The ucf, it programs only the last row.I tried to Send a '1' in all of the pins, and it put '1' only in the last pin, PIN 53.Anyone else encountered this?Thank you Quote Link to comment Share on other sites More sharing options...
Jack Gassett Posted March 14, 2016 Report Share Posted March 14, 2016 Hello, Can you please post the ucf file in question? Otherwise I'm not entirely sure what the problem you are having is, I've never encountered it before. Jack. Quote Link to comment Share on other sites More sharing options...
William25 Posted March 15, 2016 Author Report Share Posted March 15, 2016 Hi, I'm using a device that has 3 mode legs and i Tried to set them up:net "Mode(0)" loc="P102" |iostandard=LVTTL;net "Mode(1)" loc="P101" |iostandard=LVTTL;net "Mode(2)" loc="P100" |iostandard=LVTTL;it only puts out a '1' at MODE(2) and the rest are at '0'.

Jack Gassett Posted March 15, 2016 Report Share Posted March 15, 2016 According to the Papilio DUO pin diagram P100, P101, P102 would be marked on the board as pins 21, 20, 19. Does that match what you are checking? What is the VHDL code you are using? Jack. Quote Link to comment Share on other sites More sharing options...
