The 7 Series Integrated Block for PCI Express core does not link up successfully on an Intel Z77 (Ivy Bridge) platform.
This affects the out-of-box experience for customers wanting to use the Zynq-7000 PCIe Targeted Reference Design (v1.0) running with ISE 14.3 design tools on the ZC706 Evaluation Kit.
For ISE 14.3 design tools, to resolve this issue, perform the following steps:
Using an external power supply is an interim solution. A Tandem configuration bin file which will meet the PCIe specification without the need for an external power supply should be available in the next release of the TRD.
In 14.4, the ZC706 PCIe Base Targeted Reference design bin file, zc706_pcie_trd.bin, was updated accordingly with 14.4 recommendations (TX_RXDETECT_REF set to 3'b011). The changes in this Answer Record are no longer required from 14.4 and beyond.
