LCK_cycled unused DCMs

Jump to solution

Hi,

just a confirmation (perhaps obvious), from ug380 I read "the FPGA waits for all DCMs and PLLs to lock...". What  does "all" mean? If I use only few DCMs and PPLs? I guess "all" means "all used by the design". Right? I tried and it works but better to be sure.

BR

Tom

Yes, that is correct.  Any other definition of "all" would be silly, pointless, and useless.

And this is a user-selectable option.

Summary:
1. Read the manual or user guide. Have you read the manual? Can you find the manual?
2. Search the forums (and search the web) for similar topics.
3. Do not post the same question on multiple forums.
4. Do not post a new topic or question on someone else's thread, start a new thread!
5. Students: Copying code is not the same as learning to design.
6 "It does not work" is not a question which can be answered. Provide useful details (with webpage, datasheet links, please).
7. You are not charged extra fees for comments in your code.
8. I am not paid for forum posts. If I write a good post, then I have been good for nothing.
