请教:HSPICE 后仿真出错!
用HSPICE作后仿真时,
出现报错,
就是
说没有从节点到地,没有DC同路,
no dc path from node net11 to groud
但是电路中没有悬空的电容和电阻,
请问高手,这是怎么回事?
怎么解决呢?
请高手不吝指教,
不胜感激!
找到节点,
手动加一大电阻连接地。..
R00001 net11 0 1e12
Spice requires that every node in a circuit have a DC path to ground (ie node "0"). Be careful when, for example, connecting two capacitors at a node. Such a node between caps would have no DC path to ground and would cause Spice to reject the input file. To fix this connect a huge (ie 1 G-ohm or so resistor from the node in question to ground. This will hardly change the circuit but will provide that vital DC path to ground.
非常感谢!

thanks a lot
I will have a try
-----------------------------
但是没有dc通路到地的节点太多了,
至少有百个以上,
一个一个加肯定很费事的,
请问还有其他办法吗?
-----------
除此以外还有别的办法吗
可不可以修改HSPICE的仿真精度?
万分火急!
求高人的帮助!
不知道。
问题已解决,
谢谢大家的关注!
小编咋解决的阿,说说呗
其实是版图提取文件出错了
net11 may be a floating net
顶!
你好,请问版图文件提取出错问题在哪里啊?
