because the quartus do:
what is "ripple clock"?
Warning: Found 3 node(s) in clock paths which may be acting as ripple and/or gated clocks -- node(s) analyzed as buffer(s) resulting in clock skew
Info: Detected ripple clock "inst5" as buffer
Info: Detected ripple clock "myflipflop:inst14|Q" as buffer
Info: Detected gated clock "inst18" as buffer

Hi,
I think the Info is a little bit misleading. It only means that Quartus found 3 nodes which drives the clock inputs of e.g. registers. You don't need to do any buffering here, but this kind of clock generation could cause a lot of timing violations.
Kind regards
