在上面那个提示错误上，还有两行，不知道有没有用
Delete psf data in /export/home/maliangyi/simulation/floa_ocean/spectre/schematic/psf.
Cannot start up spectre.
我感觉是不是因为开头有什么原因错了，直接就没有开始仿真。
还有两句error提示
*Error* difference: can't handle (nil - nil)
*Error* load: error while loading file - "/export/home/maliangyi/Ocean/oceanScript_2.ocn"
谢谢了~

学习中！

我也才开始学习写ocean 脚本。

正在学习

我也遇到同样的问题 求解

mark一下

建议删掉 ocnWaveformTool( 'wavescan )试一下；还有就是只跑stb仿真后试一下 （前提都是你的ADE仿真成功）

ocean 脚本的学习资料谁有?求赐
