Honored ContributorCan't close timing on one clock domain
Hi, I've been struggling to close timing on one clock domain in my design, happens to be the one with all my control logic/ nios on it so is kind of important for getting into functional test....

Honored ContributorLooks to me like you have legit timing problems, as in your logic just can't run at 200MHz. You're at or well beyond the fmax for Nios II on Cyclone V depending on which Nios flavor you're running. See Table 2 in this document:
