Ну кто вам сказал, что эта опция (подтяжка резисторами) работает в 7000-ном семействе?
Посмотрите на структуру IO control block, описание Output Configuration. Никаких подтягивающих резисторов там сроду небыло.
Что касается неиспользованных входов, рекомендую вам почитать отчет компилятора в PIN файле.
Короче говоря, висячие ножки оставлять нельзя. Всякие пул-апы на выделенные входы не распространяются
Найдете в PIN файле примерно следующее:
---------------------------------------------------------------------------------
-- NC : No Connect. This pin has no internal connection to the device.
-- DNU : Do Not Use. This pin MUST NOT be connected.
-- VCCINT : Dedicated power pin, which MUST be connected to VCC (3.3V).
-- VCCIO : Dedicated power pin, which MUST be connected to VCC
-- of its bank.
-- GND : Dedicated ground pin. Dedicated GND pins MUST be connected to GND.
-- It can also be used to report unused dedicated pins. The connection
-- on the board for unused dedicated pins depends on whether this will
-- be used in a future design. One example is device migration. When
-- using device migration, refer to the device pin-tables. If it is a
-- GND pin in the pin table or if it will not be used in a future design
-- for another purpose the it MUST be connected to GND. If it is an unused
-- dedicated pin, then it can be connected to a valid signal on the board
-- (low, high, or toggling) if that signal is required for a different
-- revision of the design.
-- GND+ : Unused input pin. It can also be used to report unused dual-purpose pins.
-- This pin should be connected to GND. It may also be connected to a
-- valid signal on the board (low, high, or toggling) if that signal
-- is required for a different revision of the design.
-- GND* : Unused I/O pin. For transceiver I/O banks (Bank 13, 14, 15, 16 and 17),
-- connect each pin marked GND* either individually through a 10 kohm resistor
-- to GND or tie all pins together and connect through a single 10 kohm resistor
-- to GND.
-- For non-transceiver I/O banks, connect each pin marked GND* directly to GND
-- or leave it unconnected.
-- RESERVED : Unused I/O pin, which MUST be left unconnected.
-- RESERVED_INPUT : Pin is tri-stated and should be connected to the board.
-- RESERVED_INPUT_WITH_WEAK_PULLUP : Pin is tri-stated with internal weak pull-up resistor.
-- RESERVED_INPUT_WITH_BUS_HOLD : Pin is tri-stated with bus-hold circuitry.
-- RESERVED_OUTPUT_DRIVEN_HIGH : Pin is output driven high.
-- NON_MIGRATABLE: This pin cannot be migrated.
