Clear & Preset Logic Control
LAB-wide signals control the logic for the register’s clear and preset
signals. The LE directly supports an asynchronous clear and preset
function. The register preset is achieved through the asynchronous load
of a logic high. The direct asynchronous preset does not require a
NOT-gate push-back technique. Stratix GX devices support simultaneous
preset/ asynchronous load, and clear signals. An asynchronous clear
signal takes precedence if both signals are asserted simultaneously. Each
LAB supports up to two clears and one preset signal.
In addition to the clear and preset ports, Stratix GX devices provide a
chip-wide reset pin (DEV_CLRn) that resets all registers in the device. An
option set before compilation in the Quartus II software controls this pin.
This chip-wide reset overrides all other control signals.
