求助前辈，用Cadence仿真的图形，怎么导出用Matlab重新画

466579614

要写论文，论文要求仿真图不能是Cadence 那种仿真图。
求助前辈们，这种模拟的仿真图要怎么从Cadence 导出（截图不算），有什么教程可以在Matlab里面重新画一遍？或者其他软件？谢谢大家了

导出CSV应该就可以用Excel、origin、matlab了吧

直接打印成PDF也可以用啊

我之前的论文是cadence仿真图上取点，导出点的数据，在matlab中写几行简单的绘图代码重新画出来的。

Try a Matlab code to access the Spectre result directly

% There are two methods to access the Spectre simulation dataset

% method 2: use the Cadence-Matlab toolbox function call to read the dataset directly

用ocnPrint把曲线打印出来，读取到matlab做处理
具体用法在论坛里搜oceanref这个pdf
