glitch curiosity

Hallo friends, At simulation stage, Quartus reports some combinational glitches found, all of them under 1nS. Few questions: 1) How accurate is this in real world? 2) The curious part...

I would certainly not rely on the simulator to tell me if I'm glitch-free. Better instead to use design techniques that guarantee glitch-free operation.

Indeed! I have to get use to synch world :) After some combinational logic I have, I inserted a dff, clocked by main clock (which is sufficiently greater than this part of design, so 1 tck delay isn't important) and this signal becomes glitch-free.

After this, all my signals become nice & clean. Tnx for advices!
