If the design is using the transmitter PLL output to drive any clock
into the core (any part of the device), asserting the rxanalogreset
signal of all four channels also resets the transmitter PLL and affects
the clock that feeds the core logic. This behavior is not modeled in the
Quartus II software simulation.
shows an example of a problem configuration using the
Stratix GX 25F device. This configuration is also applicable to all devices
in the Stratix GX device family.
