Spent some time on migrating a design so fairly sure it is consistent acorss 2 PCs in the office and several versions of the design including the original example design
Basically in ISE when I press "Synthesize" it never starts and the following message is reported
I've manually re-generated the core form Core Gnerator which reports that the core is OK but cannot get past the ISE error.
Anyone seen this - I've looked through the forums for this but didn't find anything - appologies if it is a known issue.

I have the same problem migrating the PCIe core to version 13 of the tools. It seems to work fine when I migrate other coregen cores (FIFOs etc).
Doesn't work when I generate the PCIe core from scratch in 13.1 either.

This is a coregen problem that happens when it doesn't recognize some of the options in the XCO. I know that you haven't changed anything, but CoreGen sees something there take it believes should not be there. If you have the XCO in your ISE project, I recommend adding the RTL instead of the XCO. It's generally more stable for the cores that provide a lot of RTL.
