用Cadence做一个晶振起振电路的仿真,tran时有信号,在2.2ms时起振,信号峰值大约为1.2v,但仿pss/pnoise时,pss不能通过,说节点处的电压 is too small to reliably detect the period of the oscillator,不知哪位遇到过类似的问题?
如有帮助,不胜感激。
请教晶振电路的pss仿真问题
你好。请问下,你的不收敛的问题如何解决的?我也遇到同样的问题,瞬态仿真有波形,而且电压不小,但是PSS仿真时就说
V(VOUT,net34) is too small to reliably detect the period of the oscillator.
This may be because nodes with insignificant signal levels were chosen,
or it may be because the oscillator was never properly started
