For my master thesis, I need to measure the propagation delay of the modules of my implementation. I use Quartus II to do so. My goal is to measure the critical path of my modules. I have read a lot of topics that say that I need to use the TimeQuest Timing Analysis tools but it is too complex for me (I'm more a computer science engineer than en electrical one). I search and I have found that Quartus performs a computation of the propagation delay which is what I need. I have found on this website all the details :
Unfortunately, it doesn't answer all my questions. Effectively, I can clearly see what is a transition from rising edge to falling edge (a transition from 1 to 0) and from falling edge to rising edge (a transition from 0 to 1). However, I cannot see what is a transition from rising edge to rising edge and from falling edge to falling edge. I suppose that it doesn't mean that the signal doesn't change (since there wouldn't be any propagation delay).
Can someone explain me what is this transition ?
Thank you !
