AXI Bridge for PCI Express v2.3 (Rev1) - Incorrect Generation of x8 link width core at Gen2 Speed


Version Found: v2.3 (Rev1)
Version Resolved and other known issues: (Xilinx Answer 54646)

When generating the AXI Bridge for a PCI Express v2.3 (Rev1) core, the tool allows the core to be generated for x8 Gen2. 

However, the core only supports up to x4 link width at Gen2 speed. 

x8 link width is supported only for Gen1 speed.


This is a known issue and will be fixed in a future release of the core.

Note: "Version Found" refers to the version where the problem was first discovered.

The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
