Is the issue of "positive phase noise" related to MMSIM version?

bjbit

Hi,

 I am simulating PSS+Pnoise on my LC oscillator for jc and jcc jitter measurement. From the phase noise plot I got positive value at low frequency offset, which I think makes the jitter calculation incorrect. I searched and read through some old threads with the same topic. It seems this issue is connected to the MMSIM version, but nobody clarified it. I am likely working with IC61+MMSIM60, although I need to check with the server manager. So is it the case that if I upgrade MMSIM, this issue "positive phase noise" can be solved? Or is there anything else I am missing? Thanks in advance.

Regards,

  • Hi bjbit,

     

    I looked in the call tracking system and did not see any Cases for Virginia Tech Univ. with the subject of positive phase noise (I only looked within the past year).  

    If a Case is not getting proper attention, you (your server manager or whomever owns the case) can have it escalated through http://support.cadence.com .  I recommend that course of action.
