Forcing dual regional buffers

New Contributor I



Is there a way in Quartus 18.0 to force the use of dual regional clock buffers through the assignment editor while keeping the altclkctrl setting to "AUTO"?


I got 4 instances of a component and if want to use regional clock networks for all of them, one must be a dual regional clock region. However I don't seem to make it work without creating a separate ALTCLKCTRL instance for that particular case.


I've seen some posts indicating how to do it but they are for older versions of quartus and do not work with 18.0.


I'm using a Cyclone V btw.
