18 years ago --- Quote Start --- PLL Reset is not required for phase increments. It is however required for other PLL settings, M, N etc. --- Quote End --- Yeah, everything work fine for post-scale counter manipulation (not implementing phase increments). Its just the changing of the N value that's giving me grief. I know it'll kill the lock, I just can't get it to lock again afterwards. I've tried resetting it, for as long as 1,000 clock cycles. Still doesn't lock again. I've tried decreasing the input frequency, I've tried all kinds of things. I just can't get it to re-lock. But this is only on timing simulation. Functional simulation it re-locks real quickly. But it just won't on timing simulation, and I can't figure out why.
