Honored ContributorHello,
I use Qartus II web edition where LL is disabled, and sometimes small change in code causes significant change in final implementation results. I'm not familiar with LL, so I have a question - does LL allow to avoid this effect by locking parts of project to fixed logic? Thanks in advance.
Honored Contributorthat would be more like Incremental Compilation rather than Logic Lock
there's a newer feature called Rapid Recompile which is supposed to recompile only the logic surrounding your small change, also found in Subscription EditionHonored Contributoryou might try the 30 day trial of Subscription Edition to see if these features will benefit you
Honored ContributorWhy kind of changes do you mean? are they performance changes?
If you are having timing problems due to asynchronous elements and latches, the best thing you can do to fix it is to make the design synchronous.Honored Contributorgood point stepping back and looking at the problem as a whole
the tools i described are for saving compilation time, not correcting functional changesHonored ContributorHonored ContributorThe problems you are having sounds very much like not having a synchronous design - minor changes can cause the whole thing to fall over, when it was fine before. Logic locking is not going to help you much. The best thing you can do is step back and re-asses the code and make it all synchronous.
