You can configure PCIe functional mode with or without the receiver clock rate
compensation FIFO in the Stratix IV device. The reset sequence remains the same
whether or not you use the receiver clock rate compensation FIFO.
PCIe Reset Sequence
The PCIe protocol consists of an initialization/compliance phase and a normal
operation phase. The reset sequences for these two phases are described based on the
timing diagram in
