8.1
■ Added new material on root port which is available for the hard IP implementation in
Stratix IV GX devices.
■ Changed to full support for Gen2 ×8 in the Stratix IV GX device.
■ Added discussion of dynamic reconfiguration of the transceiver for Stratix IV GX devices.
Refer to Table 5–29.
■ Updated Resource Usage and Performance numbers for Quartus II 8.1 software
■ Added text explaining where TX I/Os are constrained. (Chapter 1)
■ Corrected Number of Address Pages in Table 3–6.
■ Revised the Table 9–2 on page 9–2. The following message types Assert_INTB,
Assert_INTC, Assert_INTD, Deassert_INTB, Deassert_INTC and Deassert_INTD are not
generated by the core.
■ Clarified definition of rx_ack. It cannot be used to backpressure rx_data.
■ Corrected descriptions of cpl_err[4] and cpl_err[5] which were reversed. Added the
fact that the cpl_err signals are pulsed for 1 cycle.
■ Corrected 128-bit RX data layout in Figure 5–9, Figure 5–10, Figure 5–11, Figure 5–12,
Figure 5–18, Figure 5–19, and Figure 5–20.
■ Added explanation that for tx_cred port, completion header, posted header, non-
posted header
and non-posted data fields, a value of 7 indicates 7 or more available
credits.
■ Added warning that in the Cyclone III designs using the external PHY must not use the dual-
purpose V
REF
pins.
■ Revised Figure 14–6 . For 8.1 txclk goes through a flip flop and is not inverted.
■ Corrected (reversed) positions of the SMI and EPLAST_ENA bits in Table 15–12 .
■ Added note that the RC slave module which is by default not instantiated in the Chapter 15,
Testbench and Design Example must be instantiated to avoid deadline in designs that
interface to a commercial BIOS.
■ Added definitions for test_out in hard IP implementation.
■ Removed description of Training error bit which is not supported in PCI Express
Specifications 1.1, 2.0 or 1.0a for endpoints.
