Разрабатывается плата, на которой имеется Cyclone4 GX 150 672FBGA в связке с OMAP-L138. А также питание и обвязка памятью.

Все интервфейсы типа DVI, CAN и прочее планируется сделать на мезонине. И вот начинаются проблемы с питанием банков:

- банк 3,4 - DDR2 1.8V

- банк 7 - DDR2 1.8V

- банк 6 - SRAM 2.5V. Тут задействованы все выводы банка на память. Единственный вопрос - позволит ли ква задействовать все выводы банка?

- банк 3A, 3B, 8A, 8B - refclk для ALTGX, 2.5В. Тут вопросов вроде бы нет, на соответсвующие входы идут LVDS клоки для GX трансмиттеров.

- банк 5, 8 - 1.8V связь с DSP (EMIF, uPP).




Мне нужно как можно больше оставшихся свободных сигналов со всех банков завести на мезонин. Но все равно не достаточно выводов для подключения, скажем DVI. Направшивающийся выход - использовать дифпары. И вот тут проблема - все банки с которых я могу взять дифпары питаются от 1.8V, а для LVDS надо 2.5В. Можно как-то это обойти?

Вопрос второй - на входы clk банков 3-8 завожу LVDS клоки. Поймет ли их плисина или при питании 1.8В нифига? Можно конечно завести с генераторов не LVDS, но не было бы проблем с шумами.




На мезонин пойдут также парочку GX-ов, но я не знаю как на мезонине без плисины преобразовать это в параллельный код...

Ну вот к примеру схема включения банка 7.
Как только я добавляю пин fio1 в проект (SSTL-18 или просто 1.8V), ква ругается. Но ошибка не наводит меня на суть проблемы:

Я так понимаю, что он требует, чтобы на каждые 9 последовательно (это как?) идущих пинов был хотя бы один промежуток? Что-то я не разглядел где про это написано.

Ну вот к примеру схема включения банка 7.
Как только я добавляю пин fio1 в проект (SSTL-18 или просто 1.8V), ква ругается. Но ошибка не наводит меня на суть проблемы:

Quartus хочет VREF, т.к. voltage-referenced.

Для предыдущих чипов была глава Pad Placement.
Сейчас там пишут только: юзайте Chip Planner и будет вам
счастье.
