仿真电路中的上电模块与BG的直流工作点,发现在电源电压超过一定值(10V)后,dc仿真不收敛。报错类型如下:
ERROR (SPECTRE-16385)There were 7 attempts to find the DC solution.In some of those attempt, a signal exceeded the blowup limit of its quantity .The last signal that failed is V(D7.diso:int_a) =-20.5169 GV,for which the quantity is 'V' and the blowup limit is ( 1 GV).It is possible that the circuit has no DC solution.If you really want signals this large ,set the 'blowup ' parameter of this quantity to a larger value.
求问各位坛友,有没有遇到过类似的问题,应该如何解决呢?谢谢大家!
