Описание и моделирование системы логических функций
Задание
По таблице истинности системы логических функций составить две VHDL-модели и сравнить их на эквивалентность, выполнив моделирование на всех наборах значений входных переменных. Первая VHDL-модель системы функций должна быть построена по таблице истинности. Вторая VHDL-модель должна быть построена по минимизированной логической функции (также учитывать возможность реализации инверсии функции). Тестбенч должен:
- иметь структуру, показанную на рисунке 1, включающую 2 компонента (две VHDL модели, реализующих заданную систему функций)
- выполнять подачу входных воздействий
- выполнять сравнение выходных сигналов с VHDL моделей системы функций.
| |
|---|
| Рисунок 1 – Структурная схема тестбенча (Edit) |
Рекомендуемый порядок выполнения работы
- Определить для каждой функции системы форму её реализации — прямую или инверсную .
- Минимизировать функцию, применив любой известный метод минимизации, например, с помощью карт Карно, диаграмм двоичного выбора и т. д.
- Составить первую VHDL-модель по таблице истинности, используя оператор
when ... elseи оператор назначения сигнала (<=). - Составить вторую VHDL-модель, описав минимизированную логическую функцию с помощью логических операторов (not, and, or, xor) и оператора назначения сигнала (<=).
- Составить тестирующую программу, порядок подачи тестирующие воздействий должен соответствовать порядку наборов из левой части таблицы истинности.
- Дополнительные требования:
- в интерфейсе VHDL-моделей 1 и 2 для входных/выходных портов использовать тип std_logic или std_logic_vector.
