Hi all,
I have a design with major recovery timing violation (among others).
The design wasn't written by me, I'm only editing it, so I'm not fully aware of everything inside it.
There's a photo in the attachment with screenshots from timequest with the worst failing recovery path.
I'm unable to grasp where is the ~7000 ns latch edge time in the data required path coming from???
Launch clock is 24 MHz, latch clock is 200 MHz.
I tried putting the reset signal to global resources, but quartus just ignores this assignment.
I'm working in quartus 17.1. I tried using the following assignment:
Any help would be appreciated as I'm stuck and have no idea what to do next.
Thanks for your help!
