Ошибка файла ограничений Vivado

/ 26 апреля 2018

Я пытаюсь запустить программу, которая должна имитировать MIPS, и у меня возникают проблемы с файлом ограничений. ошибка и предупреждения, которые я получаю при синтезе и внедрение кода Это ограничения для платы Basys 3, которые я использую. Также эта ошибка появилась на Vivado 2017 и Vivado 2016. Я проверил это на двух разных ноутбуках. 

# This file is a general .xdc for the Basys3 rev B board

entity test_env is
    Port ( clk : in  STD_LOGIC;
           btn : in  STD_LOGIC_VECTOR (4 downto 0);
           sw : in  STD_LOGIC_VECTOR (15 downto 0);
           led : out  STD_LOGIC_VECTOR (15 downto 0);
           an : out  STD_LOGIC_VECTOR (3 downto 0);
           cat : out  STD_LOGIC_VECTOR (6 downto 0);
           dp : out  STD_LOGIC);
end test_env;

Пожалуйста, помогите мне понять это! Я не сталкивался с этой ошибкой раньше.

EDIT: Проблема была в коде VHDL. Это было сделано для платы Nexys 2, а не для Basys 3, и при попытке применить ограничения она не работала. Спасибо всем!

Ошибка Vivado говорит вам, что:

"1 из 27 логического порта использует стандартное значение ввода / вывода 'DEFAULT' [...] Проблемные порты: dp " .

В вашем файле ограничений все ваши выводы определены с помощью LVCMOS33. Поскольку вывод dp не определен, Vivado назначит ему стандартное значение ввода / вывода DEFAULT.

Чтобы решить эту проблему, добавьте недостающий вывод, как и другие, с хорошим номером выводов относительно вашей платы и тем же стандартным значением ввода / вывода: 

set_property PACKAGE_PIN XX [get_ports {dp}]        # replace XX with the pin name defined in your board pinout            
    set_property IOSTANDARD LVCMOS33 [get_ports {dp}]
