Why does smart compilation fail for my Qsys design?

Description

Due to a problem in the Quartus® II software version 12.1sp1, you may see smart compilation fail with following messages in compilation if the project has .qip file and enables the smart compilation option.

Info (###): Detected changes in Quartus II Settings File (.qsf).
Info (###): Assignment SLD_INFO with value QSYS_NAME test HAS_SOPCINFO 1 GENERATION_ID ### has been deleted.

Resolution

To work around this problem, use command line for the smart compilation.

    quartus_sh --flow compile  <your_project_name>

    (e.g.   quartus_sh --flow compile top )

 

This issue is scheduled to be fixed in a future release of the Quartus II software.
