Hello August, SpectreRF PSS for autonomous ckts was recently enhanced to take in consideration frequency division occuring for VCOs containing frequency dividers. As a result, the final PSS fund would be reevaluated to take in account this frequency division. In the event you have multiple frequency divisions occurring in your design, your PSS fundamental will be set as the largest common integer of all frequency sources. So based on this, I may be able to trick SpectreRF to get convergence. What I suspect is that the resulting phase noise may not be accurate since both VCOs induce perturbations to each other. I was wondering if other users have been through the same exercise. Thanks for your email, Geekyfrenchy
