fdtd导出gds问题

      我想问一下,当我的结构很大的时候(11G)左右,导出成gds文件在klayout中打开,我需要运用klayout的布尔运算获得该结构的互补结构。简单的示意图如下所示,一共是两层,我需要获得1非2的结构,我的操作如第三张图。对于这种简单的结构是可以获得的,但是当操作我的11G的结构时报错,结构如第四张图。有没有什么办法可以解决呢?或者fdtd里是否有操作可以在生成gds的时候就直接获得互补的结构?

      这可能是系统显示出问题了,或者是使用C++的Klayout出问题了,参见 

      std::bad_alloc is the type of the object thrown as exceptions by the allocation functions to report failure to allocate storage.

      Lumerical导出GDS的脚本你应该在使用,除此之外没有其它的。

      建议重新启动计算机试一下。也有可能是Klayout不能处理太大文件?
