I am using SmartGuide during MAP, and even though I specify a valid device and package, it fails with the following error:
"ERROR:MapLib - Guide design part (part string = virtex5) is unknown"
Why does this occur?
This error occurs during SmartGuide if NGDBuild has been run with only a device family specification, rather than a fully qualified part specification, such as "-p xc5vlx50t-1-ff665".
To work around this problem, rerun NGDBuild with the fully qualified part specification.
This problem is scheduled to be fixed in ISE version 10.1i.
