oscillation is good sign as convergence of feedback loops takes time (convergence time) before it settles with some jitter in the steady state. It then may lose lock and re-acquire if upset. All these parameters are well known in control design.
Your matlab model may not be that good I assume. Moreover to match delays and latency and bit precision/truncation is no easy job. I suggest you stick with modelsim for now.

Please don't bring me back to Matlab LOL!
Don't you think that it is taking too much time to settle? or a 300+ microseconds is normal for convergence time?
I was thinking of group delays that you once warned me of... is this the time to discuss it?
