Hi,

in many advanced behavioral models jitter is included with Gaussian distributed random numbers, but that includes usually no flicker (1/f) noise. Generally, flicker noise increases long-term jitter more, so adding additional randomness, not every period, but in longer time steps could be a way of implementing it. Has anybody a jitter model with flicker noise or detailed references with models on this topic?

Hi Bob,

whatr I tried some weeks ago was using a CMOS inverter for jitter creation e.g. in Spectre transient noise analysis, and using AC noise sources for white and 1/f noise. It looks not bad, but is probably not best wrt efficiency.
