dear ACWWong thank you for your kindly help. my problem is below, 1,this behavior model is close loop. after 30us ,this 2-order close loop is stable.then simulate the pss analysis, so the convergence problem is confused. 2, this close loop include dividers, charge pump.vco.low pass filter.pfd. 3,perhaps , the ADE environment setting have some problems. the demo show is perfect!!! thanks
