9.1i XST - The Virtex-5 PCIE_EP block delays are not available in XST, which leads to incorrect optimizations

Description

The XST compiler in 9.1 does not contain timing information for the PCIE Block. Because of this, the optimizations on paths leading to or from the PCIE block are not optimal. This can lead to difficulties in the implementation tools.

Solution

This issue has been fixed in ISE 9.1 Service Pack 2.
