用于python的ltspice结果文件处理程序
ltspice的Python项目详细描述
用于python的LTSpice数据解析库
安装
$ pip install ltspice
用法
importltspicefilepath='Your ltspice output file (.raw)'l=ltspice.Ltspice(filepath)l.parse()# Data loading sequence. It may take few minutes.time=l.getTime()V1=l.getData('V(N1)')
测试
01-RC电路
ltspice文件（.asc）
python代码（.py）
importltspiceimportmatplotlib.pyplotaspltimportnumpyasnpimportosl=ltspice.Ltspice(os.path.dirname(__file__)+'\\01_RC_circuit.raw')# Make sure that the .raw file is located in the correct pathl.parse()time=l.getTime()V_source=l.getData('V(source)')V_cap=l.getData('V(cap)')plt.plot(time,V_source)plt.plot(time,V_cap)plt.show()
输出结果
