Hi pletz,
Regarding the create clock statements. I have one .sdc file for the entire project where all timing constraints are in place for timequest. When I compile my project normally (without using qxp files) everything works fine, no create clock statements are ignored and the design works perfectly on the board.
What I then did was set the respective components as the top level and ran the compilation. It gave quite a few warnings regarding ignored constraints which I figured was normal as I was only compiling one component and it sub components rather that the entire design.
When I import the qxp files for some of the components and re run the complilation for the entire project, it tells me that certain create clock commands were ignored. I am using the same .sdc file as for the compilation without .qxp files. This happened before I set the components as partitions and with incremental compilation turned off. When this occured, I just added the qxp file to the project and instantiated as normal. It compiled successfully but did not work and ignored certain create clock commands (but not all).
Now with the components specified as a partition, and incremental compilation turned on, it does not get far enough to do the timing analysis as it produces a fatal error.
I´m not sure if what I was doing before is correct and therefore the create clock ignored issue may not have been a serious issue
Many thanks for the help so far

Hi,
I always setup separate Quartus projects for the parts I would like to import. Maybe you can try it out.
Kind regards
