Altera Stratix V Avalon-MM Interface for PCIe Solutions - Manual (Page 179)

Date Version Changes Made
• Enhanced definition of Device ID and Sub-system Vendor ID to
say that these registers are only valid in the Type 0 (Endpoint)
Configuration Space.
• Simplified the Getting Started chapter. It copies the Gen2 x4
example from the install directory and does not include step-by-
step instructions to recreate the design.
• Corrected frequencies of
pclk
in Reset and Clocks chapter.
• Added Next Steps in Creating a Design for PCI Express to
Datasheet chapter.
• Removed
txdatavalid0
signal from the PIPE interface. This
signal is not available.
• Removed references to the MegaWizard ® Plug-In Manager. In
14.0 the IP Parameter Editor Powered by Qsys has replaced the
MegaWizard Plug-In Manager.
• Removed the Transaction Layer Protocol Details chapter. This
information only applies to the Avalon-ST interface.
• Added link to a Knowledge Base Solution that shows how to
observe the
test_in
bus for debugging.
• Corrected channel placement diagrams for Gen3 x2 and Gen3 x4.
The CMU PLL should be shown in the Channel 4 location. For
Gen3 x2, the second data channel is Ch1. For Gen3 x4, the data
channels are Ch0 - Ch3.
• Corrected figure showing physical placement of PCIe Hard IP
modules for Arria V GZ devices.
• Added definition for
test_in[6]
and link to Knowledge Base
Solution on observing the PIPE interface signals on the
test_out
bus.
• Clarified that the Avalon-MM Bridge does not generate out-of-
order Avalon-MM-to-PCI Express Read Completions even to
different BARs.
• Added register definition for Avalon-MM Interrupt Vector
register (0x0060), missing from previous release.
• Removed references to Gen2 x1 62.5 MHz configuration. This
configuration is not supported.
• Removed statement that Gen1 and Gen2 designs do not require
transceiver reconfiguration. Gen1 and Gen2 designs may require
transceiver reconfiguration to improve signal quality.
