■ Added support for Cyclone IV GX and HardCopy IV GX.
■ Added ability to parameterize the ALTGX Megafunction from the PCI Express IP core.
■ Added ability to run the hard IP implementation Gen1 ×1 application clock at 62.5 MHz,
presumably to save power.
■ Added the following signals to the IP core: xphy_pll_areset, xphy_pll_locked,
nph_alloc_1cred_vc0,
npd_alloc_1cred_vc1, npd_cred_vio_vc0, and
nph_cred_vio_vc1
■ Clarified use of qword alignment for TLPs in Chapter 5, IP Core Interfaces.
■ Updated Table 5–15 on page 5–32 to include cross-references to the appropriate PCI
Express configuration register table and provide more information about the various fields.
■ Corrected definition of the definitions of cfg_devcsr[31:0] in Table 5–15 on page 5–32.
cfg_devcsr[31:16]
is device status. cfg_devcsr[15:0] is device control.
■ Corrected definition of Completer abort in Table 12–4 on page 12–3. The error is reported on
cpl_error[2]
.
■ Added 2 unexpected completions to Table 12–4 on page 12–3.
■ Updated Figure 7–9 on page 7–11 to show clk and AvlClk_L.
■ Added detailed description of the tx_cred<n> signal.
■ Corrected Table 3–2 on page 3–6. Expansion ROM is non-prefetchable.

9.0
■ Expanded discussion of “Serial Interface Signals” on page 5–53.
■ Clarified Table 1–9 on page 1–13. All cores support ECC with the exception of Gen2 ×8. The
internal clock of the ×8 core runs at 500 MHz.
■ Added warning about use of test_out and test_in buses.
■ Moved debug signals rx_st_fifo_full0 and rx_st_fifo_empty0 to the test bus.
Documentation for these signals moved from the Signals chapter to Appendix B, Test Port
Interface Signals.
