Table 1-9 in the PCI Express Compiler User Guide incorrectly shows support for an Avalon-MM interface in variations that target the Cyclone II, Cyclone III, Stratix II, and Stratix III device families. However, variations that target these device families do not support an Avalon-MM interface.
This is a documentation error only.
No workarounds are required.
This issue is fixed in version 11.0 of the IP Compiler for PCI Express User Guide.
