首先 value=｛2*v(v1)｝；其次，LT貌似不做输入参数的迭代，所以会有这样的错误提示（如果能就直接能仿TCM了）最后N-R解吉尔霍夫的时候，只计算节点电压，所以两点电压差用｛v(label1)-v(label2)｝
I use another simulator that either almost always works/converges and only very occasionally only works/converges when I change the settings of 'TR max iteration number' and TR maximum time step, changing time step to one much larger is usually enough for the things I look at. It's set ...
