When I try to add my .sgp file to Project Navigator, I receive a message indicating that there is a device mismatch, and the System Generator project is not added. If I change the Project Navigator to target the same part as generated by the System Generator project, it is still not added.
The device specified by the Project Navigator project must match the part specified by the System Generator project when generated. If the parts do not match exactly, this message occurs.
There is a known issue in which once this message has been received, the .sgp still cannot be added to a Project Navigator project even after changing the part to match. To work around this issue, you must either create a new Project Navigator Project or regenerate the System Generator portion and ensure that the parts match before trying to add the .sgp.
This issue will be addressed in a future release of System Generator.
