The authors propose a fast method for identifying the jitter tolerance curves of high-speed phase locked loops. The method is based on an adaptive recursion and uses known tail fitting methods to realize a fast optimization combined with a small number of jitter samples. It allows for efficient behavioral simulations, and can also be applied to hardware measurements. A typical modeling example demonstrates applicability to both software and hardware scenarios and achieves simulated measurement times in the range of few hundred milliseconds.
