Date Version Changes Made
2013.12.20 13.1 Made the following changes:
• Divided user guide into 3 separate documents by interface type.
• Added Design Implementation chapter.
• In the Debugging chapter, removed section explaining how to turn
off the scrambler for Gen3 because it does not work.
• In the Debugging chapter, corrected filename that you must
change to reduce counter values in simulation.
• In Getting Started with the Avalon-MM Hard IP for PCI Express
chapter, corrected connects for the Transceiver Reconfiguration
Controller IP Core reset signal, alt_xcvr_reconfig_0 mgmt_rst_
reset. This reset input connects to clk_0 clk_reset.
• In Transaction Layer Routing Rules and Programming Model for
Avalon-MM Root Port added the fact that Type 0 Configuration
Requests sent to the Root Port are not filtered by the device
number. Application Layer software must filter out requests for
device number greater than 0.
• Added illustration showing the location of the Hard IP Cores in
the Arria V GZ devices.
• Added limitation for rxm_irq_<n>[<m>:0]when interrupts are
received on consecutive cycles.
• Corrected description of cfg_prm_cmr. It is the Base/Primary
Command register for the PCI Configuration Space.
• Revised channel placement illustrations.
